events signup rsvp

I just added an Attendees tab to all event nodes on this groups.drupal.org site. This lists all users who have signed up for an event. Signup happens by clicking on a one of the node links that reads 'i am not attending'. I'd love someone to create two graphics which will sit at the bottom of event node views which encourage users to attend or unattend an event. The current link is a little too subtle.
