Nice job for taking the lead and organizing a gathering for your group! Some things to think about as you’re planning include:
Number of attendees: if you need to cut off the RSVPs, make that clear
Date and time: make sure they are both selected with group availability in mind
Length of gathering: include an estimate of how long you think the gathering may last so people know what to expect for a time commitment
Location: in building or at a neighborhood haunt
Activity: should have a clear beginning and end for closure
What group members can bring: Empower your group to contribute by listing items for people to bring in the comments section
You can always reach out to your Cobu Virtual Community Manager for additional guidance!
