Some Users lost - How can I edit the threads and post back to original users
 

Hi All

i just had some problems with my site and lost some users.

All threads and posts are there but threads belonging to lost users now shows as guest in their usergroup. but at least it shows who posted them

my question is how can I edit these threads and post so i can change the users?

is phpmyadmin a way and the only way? is there any alternatives?

thanks in advance.

Tom
