There was a particular reason behind my hi's. To post 'hi' and get your attention. In short, it was a social hi.
I don't think the '1 Moody per team' rule had anything to do with the 0 attendance. I attribute that to the lack of awareness about the event. One fb post isn't enough for a new and informal event; a proper fb event page should have been made. And more importantly, the group needs more than 29 members. You're not going to get many people to a tourny when posting about it to only that many people, especially considering that most of them won't come, myself included. i rather do other stuff like go to your place :).
