Effective and timely communication is critical to starting a group well. If someone wants to join you, tell them a bit more about what to expect. Give them the address of the meeting location, the date and time of your next meeting, and then ask if they would like to join the group. Keep a list of everyone who inquires about the group, and note who is planning to join, so that you have a rough idea of how many people to expect. A day or two before your group meets, confirm who is planning to attend. Be sure to give them your phone number in case they need to contact you and mention anything they should know before arriving (where to park, how to get into the apartment complex, tips for finding your meeting location, etc.).
