I just did this myself and it seems to work great.
Install component, install plugin, publish CB plugin, check tab settings (make sure Quick PMS settings are good), then I also checked the CB configuration control (connections tab) to use PMS for connections notification.
I dont know how it compares to other PMS tools, other than what I have read in the joomla extension directory. I am optimistic.
By the way, are you using Nant's Profile Gallery? After installing JIM-PMS my random image scroller module seemed to fail. This is a fresh CB 1.1 and Joomla 1.0.13 install.
Thx
