You can upload them now directly from the forum software!!

(Just fixed a minor bug that gobbled up the first couple of new ones).

Simply go to your profile and look for the avatar section nearest the bottom.

Click the radio button that says "Upload your avatar" and browse to the file on your computer that you wish to use.

Hit Submit

That's it ... Currently there is a minor bug in the software that will square up and distort some of them. This should be fixed in the next service update in a few weeks
