I'd like to rid my profile of its avatar, but for one reasons or another, I can no longer edit my profile, even when logged in, even when specifically going to the go> my space > profile route. All I get is the non-interactive public version of my profile. Little help?

In your Profile, did you scroll across to see the "View/Edit Complete Profile" link?

You probably have to scroll as your website URL is so long. You should link to your portfolio as:

OH! My bad. Didn't see the scroll bar. Thanks.

How do people get those awesome little movie avatars that move and stuff? Can you make them yourself or do you have to download them?

They are animated GIFs..you can find them, or make your own in an image editing program.
