Hello !

I need to add my own PHP Form in CB Registration process,or at first login (the user must fill the form one time to access the member part)
Is it possible without alter CB sourcecode ?
Else, can you tell me which part of the code may I modify to keep it as clean as possible ?

The reason of this request is that CB Custom fields seems to be too "light" for my use :
- Make Listbox felt by custom database queries
- Make them interdependant (Options of the 2nd listbox will changes following the value of the 1rst listbox...)

After, i would like to integrate theses infos in CB Profiles.
Do any tutorial exist about creating Plugins for CB ?

Thanks a lot !
