Thanks! The Affiliate system you mentioned will work. I am trying to create the mass action, and I think I have most of this right, but I have no idea what to do after the action. Still trying to figure out INT, OPERATION, STRING and FLOAT.
Can you take a look and let me know what that should be, and what changes I need to make if any?
To clarify, I only want this to happen if a user signs up as a particular type of user, or is converted to one, so I have based the trigger on create and update, and the Joomla ACL group.
Thanks!
