Maybe it's just me?
I looked and I didn't see anything that said I had to have a certain number of posts in order to have an avatar.
I changed my settings to "show avatars"
I click the "edit avatar" option but it has the "don't use avatars" bubble selected and won't let me unselect it or give me any other options.
I don't know what else to do
I know! I'll include a screen shot!
