I have recently installed the SNAP plugin for wordpress (as part of my Magento site). I wanted to use it with a Facebook App that we already have in use with the old Joomla website. Can i use the same FB app with SNAP, or do I need to create a brand new app too? If I create a new app, will I loose all of my old blog posts from my FB page? In an ideal world I would like to have the old blog posts (that were generated by EsasyBlig) and new blog posts on the same FB page.
