Bob, thank you!
I had no idea what you were talking about in regard to
ICal yesterday. Funny thing is - I had someone asking me today if the Joomla Calendar I'm using support
ICal Data exchange. My understanding now is that ICal is the industry standard for calendar application. I'm adding 'ICal Data Support" on my wish list for a Joomla Calendar.
I tested JEvents and liked its functionalities. But it doesn't have all that we needs. I guess I'm looking for a Omega Calendar that is highly flexible as a event calendar and robust as a event registration system.
