I keep getting logged out after a short amount of time. A few times I've been replying to a post, written quite a lot (especially if it's about detailing and listing products etc) then gone to post and been logged out ...when I've logged in again the post is gone and I really can't be bothered to re-write it all again. If I click the back button it just goes to the log in screen again so there's no way I can get back what I'd written. It seems a lot quicker logging me out than on other sites I use ...is there a time limit?
