It's moreso functioning as a directory of random mac students you can play games with at the moment. I've randomly been adding people I see playing dota 2 though we should organize more events.
Not too many people are that excited for events we'll get like 10 people out of the 200 or so that are in the group to participate usually even with advance notice.
It's alive though, if you have any ideas for an event just send me or grog a message.
