My old records similarly show two people on our mailing list in Boise,
and one in Pocatello, but I haven't heard from any of them in over 10
years. Hmm, one had an unusual name, and I see that he is probably now
a professor at a university in Pittsburgh. Have to look him up next
time I go up there. Another of them I know was only interested in
Lojban as one of several conlangs, and he probably never learned the
language (and may no longer be in Idaho)
Back when LLG did paper mailings multiple times a year it was a lot
easier to find groups of Lojbanists.
Does that not, indeed, indicate a regression in the # of Lojban speakers?
