So I've changed the behavior a little bit ? If a user is found in the tracker users then link to his tracker profile. If not found then link to his GitHub page.
Nope, you can rely on me (it has small code changes as you can see) I just wanted to let you know my idea. If it's acceptable then @mbabker will review an merge
@b2z Do you want me to test this anywhere? If so, where?
