Clone linkedin.com

This project will be a two phased project. The first phase (this one posted) will be to deliver similar functionality in terms of connecting users and interaction with email as is seen in linkedin. I only need to be able to clone the section whereby people are able to request that they become connected to one another (and it will email) and also that you can view your connections/contact them. In addition, users should be able to search fields such as 'company' 'industry' Phase 2 is adding in much more functionality which I will spec out in detail, on successful delivery of phase 1
