Is there any reason to how long the automatic log-out gives you before turfing you out? Sometimes I can close the site down and come back 30 mins later and still be logged in (fine) but othertimes I'll read a thread (not lengthy) and post but that post gets lots when I press 'post' as the site then tells me I need to register. I try to copy posts before I press send, but don't always remember, then kick myself when it hasn't posted.
Anyone else suffer the same? Any suggestions?
