Ok, we're getting to be pretty much full, but we can accommodate this many and more if attendance is spread out a bit throughout the day (ie. NOT have 20 people crammed into my livingroom/dining room at one time

LOL). Hopefully its a nice day and people dress warmly so they can join me outside on the deck too.
If I've missed anybody or you can confirm, post on this thread and I'll continue to update it.
