I don't know if it's been reported, I have looked and searched but the issue is quite strange. It reminds if the time the guest message about the cookies showed, even if you signed in - it never seemed like you were.
If I goto the forums index, I get greeted by the guest message.
I sign in, I'm redirected to the homepage. I look back on the forum's index, I see guest stuff. However, I noticed I am actually signed in everywhere else and, I'm able to post this.
I should have made it clear, I'm referring to the IPS site.
