Thanks @wonderboymusic for your panel at WordCamp SF -- we found it very informative!
We were excited to see your 'Avatar' plugin here on WordPress.org and even more excited to put it to use on our site!
Unfortunately, we were only able to successfully use the plugin to add (1) avatar.
Now, whenever we attempt to upload an user avatar, the upload process completes, we receive the 'user updated' notification, but there is no visible avatar.
