Someone started following me on Twitter and so I checked them out. They have a book published by http://www.blackwyrm.com/ and I went to look at the site. It has a poor Web of Trust rating and other than their own site and their facebook page, google doesn't show me a whole lot.
They seem to be quite active though and are available in a lot of gaming stores. They have no submission guidelines though, and to submit you hit "Email us" and select "Submissions" from a dropdown.
I didn't see any real red flags other than the lack of guidelines and the poor WoT rating. Anyone have any experiance?
