[FAQ] Why are some committer names links on project proposal pages?

Submitted by Wayne Beaton @wbeaton

Link to original bug (#532140)

Description

Add an FAQ entry to the "Starting a New Project" section to explain why some committers have links and others do not.

-- When the list of committers provided for a new project proposal are rendered, a link to more information for each individual committer will be included when possible. The link will render, for example, when an individual already has a role on another existing Eclipse open source project (e.g. is a committer, project lead, PMC member, etc.). No link indicates that no existing project relationships exist for that individual.
