I'm searching a social network platform, premium or free, that is complete, with good features, but 100% customizable to add my own features, and easy to customize. I want all social network's features, but i need to add my own code, object, classes and db. So i would to use php and find a platform with an easy logic structure to handle.
I am a little confused, there are a lot of social network platform: elgg, buddypress, socialengine, but i don't understand if is possible to extend and how is difficult! :(
Elgg is a good solution. Its the award winning social network platform. If you are familiar with MVC architecture, you can add/ extend / convert elgg into anything which you can imagine.
