There should be a plugin that creates a CB profile tab with the corresponding smf profile fields that syncs those fields back to smf.
right now when u choose to handle everything through CB profile the only user profile information that shows on smf forum posts will be
-Email
-Messaging
-Profile-link
info like
website, MSN, ICQ, Location etc. have to be entered through smf profile which would mean one would have to maintain two profiles. That is insufficient i think.
As far as I know from the developer geeffland from
http://www.cbconnector.com the upcoming bridging solution for CB and phpBB, CBconnector 2.0, which will be also transformed to a SMF connecting version later, already handles syncing of profile information through CB profile to the forum profile.
There is a discussion and comparison of CBconnector and Joomlahacks SMF bridge available here:
http://cbconnector.com/forum/viewtopic.php?t=49maybe the two parties could join efforts and further syncing of joomla CB profile and SMF profile to make integration even more seemless. So far CBconnector is still alpha so it would not be a bad idea to have a plugin for Joomlahacks SMF bridge right now to sync cb profile info to smf profile info as stated above until CBconnector matures some more.
