Options to Create social network modules?

[PrestashopTrackglobe]

Hello everyone:

 

For various reasons I need to add to an online social network style some features like:

 

- Forum

- Public Profile (with other private and public data).

- Friends (Requests for friendship)

- Private messages with friends.

 

I've been watching this module exists for forum: http: //addons.presta.../966-forum.html but not if there is anything else for the rest of functionalities.

 

Any help or suggestions about how to do?

 

Thank you very much.
