The Events Calendar Network Activation

I am using WordPress 3.0 and am trying to add The Events Calendar. I have one main site and then multiple sub sites. I need the ability for multiple users to add events to the calendar and then for these events to be displayed on ALL sites. Is this possible with The Events Calendar? Is there a different plug-in that could do this?

The site is for a club, the main site is for everyone and then the all of the other clubs involved have their own site. There needs to be a centralized calendar where everyone can post their events so that everyone can see what everyone else is doing and also to avoid two clubs trying to schedule an event at the same place on the same day and time.

Thanks,
