Remain somewhat flexible with scheduling initially. This leaves the door open for someone who is not quite sure how much time they can commit. Remind the group they are coming in at ground level and your intention for the drama team is to grow together. By the end of your first meeting, the group should have a basic idea on ministry format. Initially, you may choose to meet on a weekly basis to build a solid foundation for your group.
Enthusiasm seems to be sustained when a group meets regularly.
Announce the date and plans for the second meeting, thus indicating your interest to move ahead. Group members may not be ready to make a decision the first night, so give them a choice. If they are ready to join, have them sign up and make sure you have their phone number. Give notice to the rest of the group that you will be calling them in about one week, letting them know that the offer to join stays open. Drama presentations may call for additional people at times and it's advantageous to have a list of interested people.
