The home page has an activity feed under the last games: guides written or edited and comments said anywhere, newest first. The Guides tab of every class page is now the players': anyone can write a guide for the class (the two hand-written ones are gone, their addresses lead here): the game modes and the rank track it is written for (only tracks the class is open to; the skill identifiers on offer follow the track), the order to put skill points in (one per level from level 1, shown as a skill by level grid), then the guide itself as blocks: sections with the site's band headings, cards side by side, text with your own screenshots, tables, and the minimap with your own pins on it, placed on the map's named regions so they stay right when the map changes. A preview shows the whole build while you write. In the text, @ and a few letters finds a skill, ability, item, class, SI or hostile and drops it in as a chip with its icon, its in-game text on hover and a link to its page.
Sign in with Battle.net to write one. Publishing needs a linked profile that has appeared in an uploaded replay; drafts need nothing. Readers vote a build up or down, and report one that is wrong; the class's guides list shows each one with its mark out of ten, the votes behind it, and who wrote it. Every guide can be exported as a JSON document (with a schema and a per-class format for the tools that read them) and imported back into the editor.
Every class page and every entity page has a Comments tab too, for the thing itself.
A bell in the top bar tells you when someone comments on one of your guides or answers one of your comments; the activity page lists those beside the newest comments anywhere on the site. On a thread, the comments that arrived since you were last there are marked new.
There is a chat room now, in the sidebar: messages arrive live, you can reword or take back your own, and you see who is typing. Messages and comments take reactions: a small set of faces, one click each. The @ search in every box also finds missions and players; a player named by handle is told, if their account is linked. In the chat and in a comment box, a reference shows as the chip it will be while you write. A chip's hover card carries the thing's picture. The sidebar's Chat entry carries a dot while there are messages you have not seen. A player's chip shows, on hover, their career XP, the classes they play most and who they play with most; an emoji button sits in every writing box. Every guide has a Comments tab: a thread under it, answers under answers, each one voted up or down so the best answer rises. A comment is written in the same box as a guide (markdown, @ to name a skill or an item, pictures), under the player's name and portrait.
