The forum "new post" notifications reference princehtml.com instead of princexml.com. The forum sends cookies that send a hard coded ".princexml.com" as the DOMAIN portion, meaning if you log into the forum via princehtml.com, you don't actually stay logged in except via query string tracking, which is insecure and highly annoying -- you can't click the "Forum" menu link for instance-- you end up logged out.

Sorry about that, I'm not quite sure why it is happening, but I'll try and change the settings.
