Very, Very Frustrating
When entering a reply and being at that page for a relatively long time, say 20 minutes or more (be it for leaving the computer for a time or doing some research before finishing a post or whatever) and then push reply, the forum seems to have logged me out in that time and asks me to log in again. I do so, but instead of continuing to post the reply I get an error message saying no thread specified. I try to go back to the reply form and it again presents me with a log in page. I can't get back to the textarea where I typed everything in and nothing was posted, and my entire reply is lost (and it conveniently is usually a long one when I am affected by this).
