Thought I'd add some info here for all the users trying out the new digs:
We use this same forum software on TES Alliance and browsing the forum in Internet Explorer
MAY result in some odd behaviors like floating page elements (ie search bar, tabs), dead links, lagging, script errors, and more. So if you are browsing the new forums in IE and are experiencing issues similar to what I've described, try changing browsers to FireFox or something similar.
Also, I'd wager that even though the forums are back online (to stave off the impatient hoards of confused users) there is likely a lot that is still going to shift and adjust here over the next couple days. Try to be patient, the software takes time to setup and kick the bugs out of, it also takes time to create new skins, etc, be patient, I'm sure BGS will get everything sorted.

Cheers!
