The only problem I've had with PT lately is it is constantly signing me out. I click on private messages, and it says I'm not signed in. Then I re-sign in and go to send a message, it says I'm not signed in. I try to reply to a thread, same thing. Sometimes, I can't even go back to the home page without being signed out. This only seems to happen when PT is "busy" like in the middle of the day. I don't automatically sign in, but I was always able to navigate the site without any problems as long as I didn't close it or I wasn't so inactive it timed out.
