Robust Calendar for WP

Hi folks,

I’m looking for a robust calendar that can be used with WordPress, something along the lines of JcalPro for Joomla. I’m creating a community calendar. The calendar needs to allow multiple views, popups, categories, and the ability to create custom fields to allow me to track org name, address, contact name etc. I’ve looked around and the closest I’ve seen is EasyPHP Calendar. It’s not a plug-in but it doesn’t absolutely have to be. It does what I need but there is no way to add specific fields. Also I’m not sure if it allows unlimited users.

Any ideas?

thanks
