Any ideas..

 I’m the Administrator of a club in a small community. During the past year we have doubled our membership from 10-20 and are still growing.  🙌  We do great fundraisers and have numerous service projects.  We changed meetings from every week to twice a month in hopes of improving attendance.  First meeting usually a speaker and second is usually more traditional business, etc.  My question is any hints on how to improve consistent attendance. One week we might have all but three— the next meeting we might only have three.

Any ideas of how to promote more consistency?
