I wasn't able to get this plug-in to work on legacy v.1.0.11. ERROR MESSAGE: Could not find a CB XML setup file in the package. I'll continue trying.

However, it works excellent on Joomla v1.5.12. Installed without a glitch.

Although it worked with Yahoo, AOL and a few providers, it didn't work for the ones which I need. MySpace and Facebook. It would login and load my contacts accurately, however after I send my message, I would receive an error stating the form fields weren't filled out. This happens specifically with MySpace and Facebook.
