Yes that is our custom group...
But it doesn't matter, if I tell it no one that is banned be included, banned people still come up, and I tell it to list everyone but banned people and banned people are still in the list.
We have custom member names, I can tell it to only give me commercial members and it will, or only give me members in the Subscription Online Training area and it will, but if I say, no banned members, they appear.
