Hi. Sure, I think the easiest way is to install thehttp://www.concrete5.org/marketplace/addons/stack-modal/... package, and create a modal stack with social login +http://www.concrete5.org/marketplace/addons/login_block/...

Let me know if you have any problem.

Hello,

I was able to successfully implement this method for a pop-up. However, I'm using a responsive theme called "Bold & Beautiful." When I view the pop-up on the mobile screen it's all clipped off and doesn't resize. Any advice?

Hi. Sorry for this late reply. Can you give me an url to your site? I'll try to write the css needed to prevent this problem on resize.
Regards

Nicola
