Broken link to the forum

[lerno]

The link from the main c2lang.org to this forum is broken. You get unauthorized access when you use it. You can still edit the URL to enter the forum if you know it’s working but most new visitors might think the server is down.

I also get that recently, but I don't understand why. The HTML just says c2lang.org/forum, but my browser turns that into
'http://www.c2lang.org/forum/index.php?PHPSESSID=thsgtf5corng3c6nun2cm7eo40;wwwRedirect' ...
