Wolverine,

I guess I'm definitely willing to help out with testing. I'm already running the 2.0.3 version of the CB plugin, but still running the 2.0.2 version of JSMF.
 
One small problem I've encountered in the CB plugin is with Avatar synchronization. I spent some time looking into this and it appears that if I upload a new Avatar to my CB profile it correctly updates in SMF. If however I just select a new Avatar from the image gallery, it does not update in SMF. It appears the plugin is not being called when the CB User profile Avatar is simply updated versus a new one being uploaded.

Versions are:

Joomla 1.0.12
CB  1.0.2
SMF 1.1.2
JSMF 2.0.2
JSMF CB Plugin 2.0.3

Let me know what else I can do to help!

Cheers,
Glenn
