When registering a user with a social network, choose the user name of the SMF account
This is something to keep in mind and it is very important.
Because if someone registers and has a name equal to another user, the registration is canceled, it does not allow you to register.
I've tried it and will not let me register with my account because the name is already in use, this is a big problem at the time of registration.
All this would be fixed leaving the user to choose the name of the account
