Which script is easier to modify? How easy is to modify any of them to our company needs. I will give you two examples: 1. We already have photo tagging code. We will try remove some current phpfox or socialengine profile functions and add own photo tagging function and connect it with our user database. Can be implemented that into phpfox or socialengine easily if we already have photo tagging? 2. We want to track each action a user does (if user add new comment, if user has a new friend, add new photo, ...) and put it into Home page Updates which will be developed by our developers. Can be easily inserted that our own code into home page once we develop it? Thank you Ernest
