I'm going to say this once only, due to seeing a lot of character theft recently, if you use my characters without expressed permission from me, you will get only one chance to pull them down, before copyright infringement reports are made. I take my characters seriously, and will not tolerate ANYONE taking mine. If I pull a book down, however, I couldn't give a damn at that point, since I more than likely won't use them again. That is the ONLY time you don't need permission to use a character. However, do not take that as an invitation to tell me no if I still, by chance, request them removed. That will earn a very harsh reaction. That is all, have a nice day/night.
(In a very poor mood right now from personal problems, so that's why I'm not being nice about it.)
