First, though, I want to mention that these are moderated groups,
membership must be approved, and there is a graphic that you must read
(called a "CAPTCHA") and enter text into a box in order to be able to
request membership in these groups. This CAPTCHA thing is an
inconvenience but is a requirement of Yahoo when joining a group and
helps cut down on SPAM. Moderation also helps eliminate SPAM. Messages
are usually moderated rather quickly.
You are welcome to join. We don't have lots of rules, but we ask that
you be courteous, trim your posts for the sake of those who receive
the list in daily digest format, avoid profanity and topics of an
"adult" nature, and generally use common sense.
