With all your help I am just about ready to go live with threads, I'm sure there will be glitches as there are so many more settings than the classic had. About all I need to clarify now is- when I have got the membership informed about the change, and then settled back down, will I be able to redo my import to syncronize the posts (as suggested by 'driv') or will I run into duplicate files being transferred (as read on another post). Also, why do I have to replace the 'ultimatebb scripts in the cgi_bin folder, can't I just redirect the menu item on the website to the new forum? Thanks for all the help, Tim
