well it will be a good time to get on work
this is the stuff that need to be moded :
1. mod_smf_login user links (profile, etc..) are not as they sepose to be, for example:
Redirect SMF profile link to CB/CBE: not working
2. make smf read's the avatar from cb user profile.
3. == reads the user tag line.
point is that by adding such plugin there will be forum field in the registration process/user profile that user could access to @ cb frontend instead smf's
