How to mark forum as unread

[Racescort666]

Or as I found out the hard way, don't click this button.

I wasn't sure if I should start a new thread on this feature but I figured it would be all right since there were a lot of people who were unaware of the "jump to first unread" function of the forum as well:

Yeah, I pressed that too

It was a while ago, so I have to go a couple dozen pages back to see the unread-but-not-really-unread-posts now.

I'm pretty sure I asked then too, there's no way to undo it.

I did the same too

Same happend to me. After a few days everything goes back to normal though, at least the threads front on the forum pages
