The instructions from google don't specify any need for the usual listserv subscribe command, "subscribe jstrack [your full name]" but it couldn't hurt to include such a line in the body of the message.
Once you are subscribed, you will be able to post to the list by sending regular e-mail to email@example.com.
Plain text e-mail only, please...no HTML messages. So please, as a courtesy to others on the list who may not use e-mail programs that support HTML e-mail (or don't do so very well, or simply aren't configured to do so), check your settings before you send to the list.
The JStrack group is not currently moderated, and I would like to keep it that way. HOWEVER, be advised that spamming will NOT be tolerated, and anyone spamming the group will be banned permanently.
