Thanks, Gerald English. I think many writers are intimidated by the idea of
being on a publisher's black list. There are so many more poets looking for
publishers than there are publishers looking for poets that it is only
natural for poets to feel this sense of intimidation.  But poets talk about
editors, too.  Not that it seems to matter,  since the competition is so
great.  Many magazines announce though that multiple submissions are okay as
long as the editor is informed in advance. The current Poet's Market lists
1,800 markets for poems.  Some magazines come and go quickly. Small magazine
publishing is a hard and often thankless struggle.  I have served as an
associate editor for a small magazine that was beautifully done and stayed in
business longer than most.  Quite likely it would never have folded if it had
received the support it needed in terms of having the aegis of a college or
university behind it. Shamefully, it published most of the good poets in this
state, but those same poets often failed to subscribe.  I would also like to
add that poets should show support for magazines that publish them.  I try to
subscribe to magazines that have published me.  It is their reward for having
such good judgment.  LOL
