He wants to make a magic group and then have us ask to join it.

First off, you should find out how many people in your city/town would be interested in such a group. Then, determine how often the group should meet, where the meetings should be held, how long they should be, what should happen at them, and voila. You have your group. Get contact information from all members, notify them of the meetings and important events in your area.
