(Copied stuff from various people)
OOCBacktagging: Until forever!
Thread hopping: Yes, please
4th walling: All good
Canon puncture: No. I personally don't mind, but SHIKI is the kind of guy who'd use it on other characters and I don't want to push it on others.
Romance: I'd rather base such development on things that happened in previous threads naturally, but plotting is fine. Good, fun plots can change my tune on anything. Contact me if plotting or if I'm somehow missing your subtle attempts to go for the next level or something. I'll mention it if I don't want to ship.
Offensive subjects: OOCly, I'm fine with almost anything. Can't think of any I wouldn't be able to deal with right now. Just go ahead, and I'll tell you if I find something too offensive. ICly, SHIKI may flip if you talk about his father or taking Akiha.
Preferred contact: AIM, PM, or E-mail. That's in order of preference, though PM and e-mail are pretty much interchangeable. My plurk is pretty much dead, even though I do check it from time to time. By time to time, I mean monthly or whenever I remember that thing exists. I am a bad social networker.
( IC permissions )For anything else you might not be sure about, just drop a message and I'll reply as soon as I can.
