Members
Give your chapter leaders somewhere to work.
Chapters, sections and committees run on one structure, named the way your association already names them. Each group keeps its own roster and its own officers, and their officers invite the people they want and say yes to the ones who ask. The volunteers closest to your members are the ones building engagement, and this is where they do it.
Choose what each group is called
State chapters, practice sections and a governance committee all run on the same structure, under the names your association already uses. Run as many kinds alongside each other as you like.
Let group leaders grow their own roster
Chapter leaders and committee officers send the invitations, review the requests and approve the joins. Recruiting and admitting sit with the same people, so growth stops waiting on a staff inbox.
Turn a roster into a community
Each group gets a forum, a chat room and events of its own. The conversations that would have died in a committee inbox happen in the open instead, where a member who has never spoken up can read for a while and arrive when they are ready. That is what engagement looks like between renewals.
