I'm in! This sounds way fun!!!
BabyP, my suggestion is first, regular mail. Cause who gets real letters anymore? And I never get any "real" mail so this would be super fun. I also love cute stationary.
Maybe you could come up with a list of stuff that we could all PM you with our answers and our addresses, and you could pair people up. You could ask stuff about our hobbies and interests or something, and pair us up according to that. What do y'all think?
Also, I think for BabyP or whoever matches people up, it'd be cool to NOT match people up who are in the same type of GLO. Like, don't match someone in a local with another local, or whatnot. Just for variety. But that's just an opinion.
