Where are the number of attendees on an event?

In the oldest version of the LoCo Team Portal website, when someone registered on an event, his nick name was appeared on the right of the event's screens. So everyone could view the number of attendees on the event.

Now with the new version this function doesn't appears, is there any hidden option ?
Why i can't see either my own registration ? The only that appears is the name who created the event.

For example see the next event of Ubuntu Greece: http://loco.ubuntu.com/events/ubuntu-greek-users/2512-ubuntu-global-jam-athens/

Thanks in advance
