Hm...I would almost be willing even to throw down a decent amount for one that was made in my image. I spend enough time here it would be worth it, and I want future people to still be able to enjoy the site. Maybe I should contact the think tank here.
I think it is a good idea to have because it shows your dedication to the site. I wouldn't mind having a custom one, but of course, every mod will have to approve of it before you can use it.
