My avatar is a pic of a clone trooper but it has history behind it for my character. Could you please read my profile and see if i am ok to have it. Also I have been trying to talk to the art team about me joining and they have not responded. Why?
I am sorry if i come across badly but i am a good person really (apart from being a bounty hunter.)
You can use whatever avatar you please, provided it couldn't be rated higher than PG-13. Some use avatars that aren't actually of their characters at all.
We have no way to know why the Art Team isn't responding - likely lack of time or lack of interest. Be sure you mailed the correct e-mail address (Found on the Contact Us link up above ^), and included samples of your original artwork.
Instead of adding the images to the email, you should upload them somewhere else (e.g. imageshack.us or photobucket.com) and post their links in the email, otherwise the SWC spam filter might catch them.
