Yeah...the link says "Mark all forums read". On the main page if you have read posts in a forum then the forum icon will look like this:

The "mark all forums read" will simply make each one appear like this again:
![[Image: off.gif]](https://images.weserv.nl/?url=atheistforums.org%2Fimages%2Foff.gif)
As you pointed out, it also blanks the "view new posts" page, but any thread you have yet to read will still appear unread in a forum if you go to view it.
