Forum Additional Usergroups question
 

I am trying to systematically add users to user groups if they meet some criteria. I am looking in my vbulletin database but am not clear on one of the tables. The vbulletinusergroup is perfectly clear as is the vbulletinuser table which has a usergroupid column which seems to be for the main user group. However, for additional user groups, I am expecting to find a many to many table where a single user id can have references to multiple user groups. Is there such a table or is it configured via xml files?
