I built the template for this Joomla site based on the Helix3 template framework. I am currently the Webmaster. The site serves several thousand users, and supports event management, calendars, and a membership directory.

This Joomla-based site has a custom theme that I created. It includes many interactive features, including membership management, an online calendar, and an e-invitation system, as well as an integration with Mailchimp. And I’m not only their current webmaster, I’m also a member of the club 🙂
