Social networking site

The project is a social network (with the standard social networking features - messages, profiles, a forum, groups, chat and so on). We're using the CakePHP framework ([login to view URL]). The deployment platform is Linux/Apache/mod_php. We're using git as our SCM, and we're hosting that on github (and using their builtin issue tracker). We provide access to a development VM that has an equivalent setc up to our production server. A basic knowledge of Linux is required. The developers here use Linux for development as well, but we generally don't care which tools you're using as long as the end result is good. Time to complete is negotiable.
