Starting an online message board for employees of a large company...? - how can i start playing the online tech deck game

I played with some ideas on a message line for a large company I work with others to give free rein to create their work. It is a large national company is well known that people of many employees, but there is no table, as with a specific area.

Some questions:

How the technology works to be smart, they are running?
Cost?
Time?

More importantly, what the legality of doing such a thing? I know that there are many web sites, to his horror, with businesses and employers to express, but it is the foundation that you can not cross, and to avoid dealing with legal issues?
