So I need to have a script built that will lock content until the user shares the page on their facebook. Basically, there is going to be a 'Next' button on my website, and I don't want it to become clickable until after the page is shared. Is this even possible now? I've seen script out there with the like button being used, but not the share button. The share button might require facebook connect, which would be okay. What is the best route I should go to accomplish this? I have developers, so we will be building from scratch.
