...Unless they've been listed as such.
I've gotten several notes regarding people wanting to buy some of my characters, and I'm sorry, but unless I come out and say that they're for sale, the answer's gonna be no. :
( Especially since a lot of them were characters I adopted from friends and still use quite often.
I still use deviantART. I just go under a different name. If you see someone using a character that I own, PLEASE LET ME KNOW, because I didn't sell it to them.
If you see someone using a character that I own, note gyngercookie and she will relay it to my new account.
EDIT: Don't note my friends asking to buy characters. Especially if I already told you no. That's rude, sorry. :/ /EDIT
I really hate to seem rude as doing this, and this is to no one in particular (more for people who may have the same question), but my characters are like my babies and like stated before, I don't get rid of them whenever someone offers. If I wanted to get rid of them, I would have posted a journal.
Sorry for any confusion.
