Summary of changes

New feature: Battle.net Community support

• functions.lua — new addon:renderCommunities(frame) renders one collapsible section per subscribed Character-type club (in-game Community), excluding the player's guild. Shows Online/Away/Busy members, sorted alphabetically, with a gold header to distinguish from guild (green).
  • Class-colors names via GetPlayerInfoByGUID(guid) (no inspect/group requirement).
  • Falls back to the guild roster (addon._guildRosterByGUID, built in renderGuild) for level, since the Club API doesn't expose it directly.
  • New right-click menu: showCommunityRightClick(player) (whisper / invite / who).
• config.lua — new "Communities" options group with a ShowCommunities toggle.
• Socialite.lua — ShowCommunities added to the saved-variable defaults (defaults true); new events CLUB_MEMBER_UPDATED and CLUB_ADDED registered so presence changes and post-login club data trigger a refresh.
• i18n/enUS.lua — new locale strings for the Communities section.

TWW (12.x) compatibility fixes

• functions.lua — right-click menus rewritten with MenuUtil.CreateContextMenu (the old UIDropDownMenuTemplate path was removed in TWW and previously just printed "temporarily disabled, sorry!" instead of working).
• Socialite.lua — GUILD_MEMBER_ONLINE/GUILD_MEMBER_OFFLINE no longer exist in TWW; event handling now relies on GUILD_ROSTER_UPDATE (which Blizzard fires for all guild state changes) with a 0.5s debounce to coalesce bursts (e.g. several guildmates logging in at once).

Bug fixes

• Socialite.lua / functions.lua — guard against calling guild APIs when not in a guild (renderGuild now bails early via IsInGuild(); data-text click handler no longer calls ToggleGuildFrame when ungrouped) — previously could throw nil errors for unguilded characters.
• functions.lua — collectGuildRosterInfo nil-coalesces GetNumGuildMembers() results in case the API returns nil mid-load.
• i18n/enUS.lua — fixed a copy-paste typo: minimap tooltip string said "Show the Scoreboard minimap button" instead of "Socialite".

UX improvements

• functions.lua / Socialite.lua — tooltip sections (Battle.net, Friends, Guild, each Community) are now click-to-collapse, with state persisted per-section in saved variables, and the tooltip re-renders in place rather than requiring a reopen.
• Friend/guild "right-click" and "whisper" actions now consistently use Ambiguate(name, "none") for display, stripping realm suffixes while keeping the full name for API calls.

Cleanup

• Removed dead code: unused tprint() debug serializer, legacy getRightClickFrame() dropdown-frame helper.
• i18n/enUS.lua reorganized into labeled sections (Core / Tooltip headers / Config panel groups); removed several stale _DESCRIPTION keys that were either already commented out or unreferenced anywhere in the codebase (confirmed via grep — no breakage).
• Reformatted all 4 files from tabs to the project's standard 2-space indentation (.editorconfig/stylua.toml).

Open question for reviewers

• i18n/enUS.lua adds L["TOOLTIP_COMMUNITY"] = "Community" but it isn't referenced anywhere — community headers currently use the club's actual name (club.name) instead. Harmless, but flagging in case it was meant to be used as a fallback label.

Thanks for contributing!

These changes all look fine, but I'm unable to verify the Communities feature. When I load your changes, I see the configuration for communities, but I don't see them displayed in the tooltip. Is this verified working for you?
