I don't know why but all the threads in a forum are sorted by the number of posts in it and not by the last post criteria. It is only when I am signed in. When I sign out and browse the forums, all threads are sorted by last post. I have tried to search where this option could be but I haven't been able to find.

Please Help !!!

On the Sort Threads box (by default at top and bottom of each page), choose Newest Replies or Last Post Time.

Change your sort order in the UserCP (http://forums.slickdeals.net/profile.php?do=editoptions)

Thanks slickdeals. Found it
