The current one is something like the seventh of these I've participated in. Of those, two of them have been mailed within a reasonable time from the designated mailing date. Another was mailed on time, but disappeared in the Post Awful somewhere—in the same city I live in! The rest have mailed late. Every. Single. One. The mailing date for this latest exchange was May 31. I'm still waiting.
And I'm profoundly disappointed. I don't think I want to play this any more.
