Strange behavior on namecard.

Hello,
When i click on register link on namecard A, i get perfectly redirected to the registration form, but if i want to register through another namecard B (to be friend with the owner of the namecard B), i still get redirected to the registration form matching the namecard A. Indeed, sometimes users change their mind, so i think it'd be convenient to be redirected to the registration form with the target contact.

And, i'd like member be automatically friend with the owner of the namecard when he registers, currently he must accept Friend request. Is there any way to skip this.
