We've been using the cloud membership management software, Wild Apricot, for several months now just to manage our member sign up and expiration notices. We've also used it to send email blasts to members.
This platform can go way beyond that, so you'll find that https://coastalcyclists.wildapricot.org now has all the content that our https://coastalcyclists.com website has, plus more features. In the fairly near future we will probably move the main website to this new platform, thus unifying almost all our communication and subscription efforts.
Keep an eye out for more content and more news as we beef up our online presence. Check out the forums for a good way to communicate with other members.
