How the forum is organised
The forum has a four-level hierarchy: Sections contain Subforums, which contain Topics, which contain Posts.
The forum index returns sections, subforums, newest topics, newest replies, latest post summaries, topic counts, reply counts, and supported reaction emojis. Subforums list topics with pinned topics first, then newest activity.
Topics
To start a topic, open a subforum, choose New topic, enter a clear title and the first post, then select Create topic. The new topic opens with your post at the top.
Creating a topic uses the shared post cooldown: base 2 hours divided by your community level. The cooldown is shared with Feed custom posts.
Moderators and admins can pin a topic so it stays at the top of the subforum, lock a topic so normal users cannot reply, edit topic metadata, or delete the topic.
Posts and reactions
Replies are normal forum posts inside a topic. Creating a reply uses the shared comment cooldown: base 30 minutes divided by your community level. Replies are blocked when a topic is locked unless the user is an admin.
Every forum post can receive one active like per user, and you cannot like your own post. The first counted like gives the post author 10 XP.
Forum reactions use the emoji choices shown below a post. You can set one reaction per post, choose another to change it, or click the same reaction again to remove it. Reactions are counted publicly but do not add XP.
Reply notifications
When someone replies in a topic, the topic author and relevant participants receive a notification. Open it from the dashboard header as explained in Notifications and Reports.
Bug confirmations
When a forum topic or reply is accepted as a confirmed bug report, its author receives 50 XP, their confirmed bug count increases, and bug achievements can unlock.
Forum bug confirmation uses the same reward amount as feed bug confirmation. The achievement side is documented in Experience and Achievements.
