We have a classified ad board on our site. People post their
names and e-mail so they can be contacted when someone wants
to buy, sell, trade, whatever. Sorry I guess ya'll know what
classifieds are. Anyway would it be spamming for me to use
their email address to send out a monthly newsletter? They
are not voulteering their email to be used for that, however,
I'm allowing them to use our classifieds. Opinions?
