Ok.
Soooooo I have this one character that I am DYING to put on DeviantArt, because she's really super awesome. . .well a lot of my friends think so anyways >.< I also think other people would like her as well. My only problem is, she's not copyrighted oranything, so I'm not really sure what to do.
See, I don't want people stealing her, and calling her their own, but I also really want to start putting my pictures up on DA again, because lately, all I've been drawing is my one character.
So I need an opinion. tell me if I should:

A) Post her anyways, and hope that she is never ever ever stolen.

B)Not post any pictures of her and just wait to get her copyrighted.

Please, please, please tell me what I should do! I'm in dire need of some help. >.<
Plus, if anyone knows anything about getting things such as this copyrighted, please tell me any info you know! I would be very appreciative!!!!

Thanks Mucholy!!!!!!!!!! ^-^
