hi Chris Oliver on the @mentions episode can you share the css you use to show both user name and profile picture?
I don't believe there was much (or any?) CSS in that episode that I wrote. All the source code for that episode should be here: https://github.com/gorails-screencasts/gorails-episode-78
Atwho.js does include some CSS with the library to style the mention box: https://github.com/ichord/At.js/blob/master/src/jquery.atwho.css
