I've been anticipating this thread! Finally, I'll be participating this year.

Is there a general rule of thumb of stamps per envelope? I live in America and obviously it's just one stamp for the other members here. But internationally, i'm fuzzy on how many I should put on.

Won't submit my info quite yet. I'm trying to do the math on postage cost and see how many other people sign up as well so I know how much I'll be spending

Deadline?
