It would be nice to see some different ones. Im getting tired of all these ones...I want to smash my screen in everytime I see that bloody Penguin shaking its head
Ask David if you want a custom avatar. Upload it and show it to him...he might allow it. As far as putting one in your User CP, you're gonna have to wait to become a Moderator before you can get that option.
i think not having much choice can be good, it encourages people to post sensibly in order to gain Davids respect and therefore a custom avatar/become a mod
i dont mind the penguin shaking its head
