Thanks, silenus!
Oops. There was supposed to be a “too” in my previous post. My bad. I want people to take part in any and all exchanges here. They are fun!
I plead nolo contendre.
No worries.
Anyone else wanna take part? Still room for lots more!
I will participate but I have to send either handmade postcards, or postcards that I bought overseas. I hope that’s o.k.
I’ve received homemade cards and they’ve been great. I’ve sent homemade cards as well. I’d think cards from overseas would be fine, esp in these uncertain times 
!
But of course!
Crud, I thought yesterday was May 29. But no, I have to wait another week to get my postcard assignments. Rule 7 is sooooo onerous.
Just think: six more days for other Dopers to sign up!
I just checked my small stash of cards & post cards and I have more than I thought I did, so I’m in - PM was just sent!
Excellent!
I’m getting oddly excited about getting a postcard from a total stranger. Hurry up, Friday!
I’ll join in also. Have sent PM.
I am in!!
Tomorrow’s the sign-up deadline. C’mon in, the water’s fine!
The deadline has now passed, and I just sent out PMs to everyone with the names and addresses of those to whom you should send your postcards in the next two weeks, that is, by Fri. June 12. (See Rules 4 and 5 above, especially). All addresses are in the U.S. unless otherwise noted, and everyone has at least one non-U.S. postcard recipient in his or her group. There’s no need for anyone to send extra cards, as the numbers worked out perfectly, but if anyone wishes to do so, please say so in this thread, and others are welcome to then swap home addresses with you via PM.
Thanks, everyone, and have fun!
Postcards are in the mail; Mailman Eddie will be here in a couple hours. I am now at Rule 7. The Onerous Rule…
Oops, too late.
Recipients received; I’ll post again when I post [the cards] 
I have to say sorry in advance to my recipients. All three cards will go from Germany to the USA, which will take about a week from my experience anyway, and I won’t be able to send them before June 6th or so because I ordered cards that won’t arrive earlier. But I promise to post them before the deadline.
I’ll be happy to send you a card if you want to PM me your address
