Membership is not growing, because people say they can just pay $10 more to attend every event. We would like to control event registration to only allow guests to attend 3 times and then suspend them...taking them to a page that tells them the benefits of being a member and encourages them to apply now. This could easily be managed in the Events section using Contact levels. You would need to require a password registration on all public registrations. Yes, there will be a few people that use a different email address to get around it, but this would greatly bolster our membership levels.
