 # FAQ & Tips
 
-This page explains how Pick'n'Play works in plain language. Each answer includes the small rules the backend enforces so you know what to expect.
+Pick'n'Play helps a small group collect game ideas, score them, and reveal a ranked list without endless back-and-forth. Everything below is written in plain language and reflects the exact rules the backend enforces.
 
 ## Accounts & login
 - **How do I create an account?** Register with a unique username (max 24 characters), a password, and a display name (max 16 characters). The display name is required because it is shown beside every suggestion and score.
-- **What if I need admin powers?** During registration, enter the admin key your host shared. If the key is wrong the request is rejected; there is no way to “upgrade” yourself later without re‑registering with the correct key.
-- **Can I change my display name later?** Yes. Use the profile/name action in the app; it updates immediately and is required before you can suggest or vote.
-- **Why does login sometimes fix my missing name?** If an old account somehow lost its display name, logging in auto-fills it from your username the next time you sign in.
+- **Do I need admin powers?** If you were provided with an admin key, enter it during registration. If the key is wrong the request is rejected; there is no way to “upgrade” yourself later without re‑registering with the correct key.
+- **Can I change my display name later?** No. Pick it during registration and keep it; there is no UI or API to change it afterward. (Only legacy accounts that somehow lost a name are auto-filled from the username on next login.)
 
 ## Phases at a glance
 - **Personal phases.** Each player tracks their own position (Suggest → Vote → Results). Clicking “Next” moves you forward; admins can move themselves backward. Moving forward always clears any “finalized” vote flag.
-- **Results gate.** You cannot enter Results until an admin opens them. When results are opened, everyone is pushed to Results automatically. When results are closed, everyone returns to Vote and all ballots are unfinalized so people can adjust scores again.

 ## Suggesting games
-- **How many can I add?** Up to 5 suggestions per player while you are in the Suggest phase. An admin-granted “joker” lets you add one extra game during Vote (details below).
-- **Required fields and limits.** Title is required (max 100 characters). Genre (50), description (500), and links (URLs up to 2048) are optional. Min/max players must both be provided or both left empty; values must be between 1 and 32 with min ≤ max.

 - **Image rules.** Screenshot URLs must be http/https, end with an image extension (png, jpg, jpeg, gif, webp, avif), be publicly reachable within ~3 seconds, avoid redirects, and be under 5 MB. Links to local/private hosts are rejected for safety. If you omit a screenshot, that’s fine.
 - **Other links.** Game and YouTube links must be http or https; any other scheme is rejected.
-- **When can I edit?** In Suggest you may edit any field. In Vote you may edit everything except the title (it stays locked). In Results you cannot edit. Admins can edit any time.
-- **Deleting a suggestion.** You can delete your own suggestions while you are still in Suggest. Admins can delete at any time. Deleting a game also removes its votes and breaks any duplicate links so nobody gets stuck with orphaned data.
-- **Why was my suggestion blocked?** Common reasons: no display name, already at the 5-limit and no joker, title too long/empty, invalid or unreachable screenshot, min/max players missing or out of order, or trying to add while in the wrong phase.
+- **What can I edit?** In Suggest you may edit any field. In Vote you may edit everything except the name (it stays locked). In Results nothing is editable. Admins can edit any suggestion at any time.

 ## Jokers (late additions)
 - **What is a joker?** A one-time extra suggestion slot that only works while you are in the Vote phase. An admin must grant it to you.
-- **How it works.** When you use the joker to add a game, the joker is consumed immediately, your ballot is unfinalized, and every player is also unfinalized so the new game can be scored. Admins can grant you another joker later if needed.

 ## Voting
-- **Who can vote?** Only authenticated players in the Vote phase with a display name set. If you removed your name, set it again before voting.
+- **Who can vote?** Only authenticated players in the Vote phase. Because display names are fixed at registration, there is no “set name first” step during voting.
 - **How to score.** Use the slider to pick a whole number from 0 to 10. Anything outside that range is rejected.
-- **Linked duplicates.** If an admin linked duplicate games, changing the score on one updates all linked siblings automatically. Scores are stored per group, not per card.
+- **Linked duplicates.** If an admin linked duplicate games, changing the score on one updates all linked siblings automatically. Scores are stored per linked group, not per individual card.
 - **Finalizing.** Toggling “Finalize” locks your scores so you cannot change them. Toggle it off to edit again. Finalize is only available in Vote; it is cleared automatically if a joker adds a new game, if an admin links/unlinks games, or if results are closed and you are sent back to Vote.
 - **Voting after changes.** When new games appear or links change, your previous votes for the affected group are cleared and you are unfinalized. Check your list and rescore everything before finalizing again.

 ## Common errors and how to fix them
 - **“This endpoint is available in the X phase.”** You are in the wrong phase. Advance with “Next” or ask an admin to move you back.
-- **“Set a display name…”** Add or restore your display name before suggesting or voting.
 - **“Screenshot URL must be http(s) and end with an image file extension.”** Fix the extension and make sure it is a direct link, not a page or redirect, and the file is smaller than 5 MB.
-- **“Score must be between 0 and 10.”** Pick a whole number inside that range.
 - **“You have reached the 5 suggestion limit.”** Wait for Vote and request a joker if you need to add more.

+- **Admin key errors.** If you see “Invalid admin key,” register again with the correct key provided by the host, or leave it empty to create a non-admin account.
 
 ## Data and privacy
 - Suggestions, votes, and phases live in a shared SQLite database. Logging out clears your auth cookie; deleting your player (admin action) also removes your suggestions and votes.
