I reallllly wanted to come last year, and this year ... *fingers crossed*. If I can make it, I definitely will! The 17-18 wouldn't work for me, but either of the other two weekends would.
And I didn't mark down "host something" or "teach something" because it's Early and I've had no coffee, so I can't think of anything that I could possibly be able to teach anyone. Apart from how to drink coffee, which I hope people know how to do. :) But I'd be more than willing to help out in any way you like!
