Is anyone else getting an "are you sure you want to leave this page?" pop-up whenever they try to leave the boards?
I think I might have found a way around this, at least for posting:
Type up your post, then add some text at the end (this can be literally anything). Then, if you post gets 403'd, remove the text and try again.
I actually stumbled upon this by accident with my signature -- I'll try to post something with my sig, and if I get 403'd, I remove the sig and it works.
