Specialized Extensions for Your Joomla Site
The following list includes extensions I have either used for client websites or for my own sites, or both. This list gives you an idea of the many extensions we can add to Joomla to customize your site. Remember, all extensions integrate with Joomla's core functions rather than hacking the core, so the extensions also play well with each other.
JEvents
Calendar extension with all the features you could want
RSVP Pro
Optional Registration add-on to JEvents
