Get ids of users in secondary usergroup

[steveheinsch]

I am trying to get an array of user ids of users who are a member of a particular secondary usergroup and then remove them from that group.

I know how to change the usergroup and usergroupids via the user datamanager, but can't find an easy way to get a list of ids of the users in that secondary usergroup.

Any pointers would be appreciated!

Thanks!
Steve

you would need to write a query which pulls member ids with the usergroupid in the membergroupids field
