Hello Perry here I found this through a Facebook story today and found it to be quite true.
Here is a clever Article about Cons/Scifi/Fandom I found interesting. as working as a volunteer at many cons there really is not any prep by some off the panel hosts so read this article by Rachel Caine on her Blog Ink and Bone.
ps. I hope Ms/Mrs/Mis Caine is not upset that I am forwarding Her article if so send me a note.
