The rules are the same as usual. First off, you need to send an email at reviews@(no-spam)gryphonwood.net with the header "SUMMONER." Remember to remove the "no spam" thingy.
Second, your email must contain your full mailing address (that's snail mail!), otherwise your message will be deleted.
Lastly, multiple entries will disqualify whoever sends them. And please include your screen name and the message boards that you frequent using it, if you do hang out on a particular MB.
Good luck to all the participants!
