I have a question about how these avatars work (I think that's what the pictures under people's names are).
I appears you go to the Edit Avatar section and put in the web address of the photo you want to use, but can you just use any photo you find on the web? Do you have to somehow be "hosting" the photo? Does the person who put up the photo on the first place care if it's being used elsewhere?
How does this work?
