Can we keep Joomla users and CB users separate ? - Joomla! Forum - community, help and support

hi,

i couldn't figure out search terms use on google want keep both joomla , cb registrations active on site , keep joomla users , community builder users separate......

which means users registered through joomla default registration not cb profile or show in cb user's lists or show in cb users search results......only users register through comprofiler registration form cb profiles , show in cb users search.....etc etc.

now possible ? or default possible , missing ? or there extension ?

can please share thoughts on ?

thanks,

sean.
