Yes, that is the OLD board address, to the OLD gr. What we did when we updated was went from /forums/ to /forum/ and updated the .htaccess file for the re-direct to these forums. Most people changed their bookmarks, some didn't, and we just haven't removed the old forum folder yet.
Either that or they are still performing secret operations behind our backs and foisting it off on changing the root directory of the forums. zomg! But it's possible that what dem is saying is true
We are working on secret operations, but no one except people under specific IPs can view the web page, and it requires a login for each user under a particular IP =P.
