Whenever I try to log on or Sign In I get an error that seems to say the cookie is corrupt. I have to delete all cookies and Temporary internet files cached on my PC and log in all over again. It seems to happen every time pretty consistantly and therefore the site doesnt log me in automatically, I also have 0 posts now. Here is a screenshot.

I am having the same problem. But I have two account names. It works on one but not on the other. I have two accounts because I forgot the username on the first account. Long story. Anyway one account behaves like Avalanche's problem. Have to get rid of cookies and start over. Get the same error screen when signing out.

Hope this helps
