Tusande, if you're offering Aries character, create topic in Aries marketplace. I'm moving topic, next time use appropriate subforum.
P.S.
I think I don't have to remind anyone that character buying is a really easy way to get scammed.
Having a signature is like keeping a gremlin.
Just don't overfeed it, don't make it wishy-washy and you'll be a good responsible Signature Keeper :]
