I need a component for Joomla that runs off of a Google calendar.  Events will be added on the google side of things, but I need to add features on the Component side:

1.  Ability to invite guests via email for each event on the calendar.

2.  Ability for guests to approve or decline invitation and that information show up on the date.

3.  Program sends out a weekly invitation to the guests until they respond.

Please provide your IM so we can discuss further details.

Thanks!
