RE: my own avatar
I was told you could use anything you like for an avatar , find any picture that you like and right mouse click on that picture then copy to your documents or your desktop.
Then go to your profile and click on avatatr and upload , it should work but if you have to resize the picture theres a way to do that too.
Don't forget to click save and / or apply at the bottom for your profile screen other wise it might not show up the first time , good luck and let me know if you need any more help.
