I thought DrenDran's was the best one, although its the only one I've been to. DrenDran's party even got more users than Kalphiter's (128) which is a record I think.
I thought Kalphiter had a party which got into the 150's once.
But we probably got the all time second place, which is more than acceptable.
I plan on hosting it again next year, but obviously I've learned a lot from this and hope to make good use of what I've learned.
The build and 'activities' weren't really handled by me though. Now that we've gotten some publicity I hope we can recruit others to help build.
