Making mass changes to users based on secondary usergroups?

[tsptom]

I know it is frowned upon to wake old threads at vb.com, but the above code was very helpful for what I am trying to do - add member to secondary usergroups systemically.

To take it a step further, does anyone know how you would remove a specific secondary usergoup for a member systemically?

I want to be able to add and remove members from specific secondary usergroups based on being a paying subscriber. The above codes helps me set them when they subscribe. When they cancel they need to be removed from that usergroup systemically.

Any ideas? Thanks.
