We have two little lists. One gets a Newsblast every time we have a new issue (that's the Reader list) and one gets a Newsblast every time we send out a new Call for Submissions (that's the Contributor list).
We have never shared our lists with anyone, though occasionally, to pay the bills, we have sent out an ad email or two directly from our own server. We haven't done that in over a year, though, and we only send out about 1 message a month. We're nice people.
Join us, won't you? Just pick the list (one or both!) that interests you.
