ColdFusion calendar app suggestions?

I have searched the forums and found no useful suggestions in the past year so I thought I would ask this question, forgive me if it has been asked before that. I need a calendar for classes that is user searchable and preferably creates userfriendly (read search engine friendly too) urls. It would need to allow links in the event description and would be nice to allow users to sign up for reminders or send the link to a friend. It doesn’t need to allow users to add or update events though. Any recommendations?
