If you are a member of a campaign, the site will help track which forum posts you have read and which one are new. If any posts are unread, a 'new' bubble will appear on the forum, and next to forums and threads you have not read yet, to let you know there is new content.

The unread status is tracked by Thread, and a thread will be marked as unread if there are any new posts since you last visited (except your own of course). A forum will be marked as unread if there are any unread threads in that forum.

If you viewed a particular thread already, but didn't get to reading all of it, or if you want to mark the thread to check it again later, you can remark the thread as unread, using the Mark Unread button in the top right of the thread, next to the title.

To clear all unread marks, you can either visit the thread, or click Mark all read in each forum, top right corner next to the Forum name or Mark group read in the forum overview to clear all forums in the group
