Recently I've gotten three PM's from different authors. They all started out as friendly notes complimenting a post of mine, but then quickly turned into a long sales pitch for their books. To me this is spam. Please don't do it. I realize most of the writers here are great people who follow the rules and all and I am sure the three who PM'd me didn't mean their messages to come across like spam. No hard feelings or anything, just thought I'd gently point it out.
