I require people to introduce themselves in an introductions category. Every time they do, I add them to a group indicating they have done it.

I would like to be able to contact people who have NOT introduced themselves, and remind them to do so (it’s a requirement).

Thus, the inverse of the “already have” group… the “have nots”.
