Okay... I think it's time for some shameless advertising. Draw a pic relating to something you want to advertise and add a link. It could be adoptable, it could just be a piece of really good art you've drawn, it could be a journal talking about your commissions. Whatever you want.
My iScribble gallery, featuring a lot of the random craptastically awesome art of mine which I screen cap. Although Muro is supposed to do a lot more, the iScribble paint-chat I mess with has much tighter control and responsiveness, and can be fun with real-time group drawing.
Wouldn't the Thumbshare forum work for that then? :I I'm not sure if people will draw what they want to advertise, as simply posting an already made picture is much faster
