Tested on 3.0.0
With the introduction of secondary groups in vB3, querying your database based on group memberships isn't as easy as it used to be. A custom script is required to determine group membership status.
To remove current signatures for all members of a group you can upload the attached file to your forum directory and run it from your browser. You need to change this line at the top to the usergroupid of the usergroup for which you want to remove signatures.
This file will remove current signatures for all members of $groupid, that includes both primary and secondary memberships.
BACKUP FIRST!
