Mandatory field on registration with cb_connect

Hello,

I created a field to hold the mobile number "cb_mobile_number" and I have it mandatory on Registration.

Now I installed cb_connect, and if a user registered using facebook or any other he will not be prompted to enter the mandatory mobile number field.

I am sure there is a work around but I can't figure it out. What I want is to prompt the user after he register;using facebook or other, to enter the mobile number, any hints?

thanks,

They can supply it in profile edit with accepting that they may never supply it or use the pre-fill mode instead of single sign on.

The mode can be changed within CB Connect > Parameters > Provider > Registration. Pre-fill will fill the registration page with as much information as it can then they'll have to complete the registration as normally and it will still link the accounts and they will be able to login via Facebook for example.
