I dropped the table :(

Well, that's quite a big problem You should ask your hosting provider whether he can give you your database backup (most of them do that for free or just a little money), because otherwise you will lose all your users' accounts. (True, you may change the IDs to the old ones after they register, but that might be kinda hard (depends on size of your forum)).

Anyway, this code should create the table with 2 users - Guest and FCKeMo (with admin rights) and pass 123456
