The review is on uddeIM 0.4, but the current version of uddeIM is 0.4c.
Things that changed from uddeIM 0.4 to 0.4c:
* Username lookup when composing a message
* It reads your Community Builder Connections and lists them as direct link when composing a message
* Natively integrated with Community Builder version RC2.
* Natively integrated with Simpleboard after version 1.1
as well as some minor bug fixes. With udde, everything is fully CSS:ed, so you can completely adapt it to your own website's layout without touching the code.
