Came here and was logged out, so went to log in and got:
"You are only allowed 1 session at a time. You had 1 other active session that was terminated."
I never visit this site on any other computer and I didn't have another browser or tab open.
Bug, I hope? Or has someone been in my account?
Ok, thanks KetchupMaster! I haven't cleared my cookies but I'm using Chrome so it might have done something without my permission. @_@
OR the ATTACK of a virus... It stole your password and will soon pretend to be you and spam the site to earn thousands of GB points which it will then donate to itself... 
Good idea! (Not like I'm going to do that or anything...) :$
Did you clear your browser cookies? or previously use it in a different browser and not log out?
I looked at the page access log for your account, and as far back as I looked the pages your account has accessed have been from the same ip address. Probably nothing to worry about, but you should probably change your password just incase.
