We have a Joomla based 2.5 site that needs s "Content Gate" that pop's up asking users for their email address in order to see the content behind the lock. In addition if we could have social media functions included: Facebook Page Like, Google +, Twitter etc.
This will probably need to be a plugin that allows customized information related to the social media platform, but also allows us to designate what pages the lock needs to be on.
We need a way to track the information so a user is not asked over and over again for the required actions.
Think "Like Gate" From a Facebook application.
