As I navigate around the forums, I keep getting logged out and have to sign back in. The first time I noticed a problem I was posting a reply in a thread I created a while back, when I was told I didn't have permission to post in the thread. I clicked on advanced reply and got a web page load error, clicked back button, and tried to post and noticed that I wasn't logged in. I logged in and clicked to reply with quote, and it worked that time.
Several times since I have noticed I wasn't logged in.
