user dashboard

In the site I am endeavoring to build, the User "Member", IS the most basic content entity. I am trying to build an specific industry hierarchal structure that displays the members' resume and other professional data as well as providing social networking environments for them to interact on common industry issues.

I suppose the substructure is similar to a Job Site where Job Seekers display their experience, skills and product output, and Possible Employers are also job seekers where everyone can discuss their common interests via postings (Comments, Blogs, Discussion, Calendaring of industry events etc.)
