T-AMLIT (teaching American literature) is another possibility, but there
is no "free" discussion.  The moderator(s) decide(s) what goes through
and what doesn't, and then it is "cut," "censored," and otherwise
"condensed" to fit into a designated theme.  And on top of that, I've
seen very little reference to Twain.

I'd also like to know any other addresses.  Are there any other groups as
lively as this one?
