Hi is there a mod for this? Facebook

[luism]

Is there a mod or some code someone can recommend for me to change so the only way to register is to use the facebook option?

I would like facebook google+ and linkedin but facebook will do..
Any ideas or suggestions as to how to accomplish this?:confused:

In the search above, search for Facebook/4.x Mods/Title only I am sure you will find something. Good Luck
