How do I add a personal title?

[calldaffer]

This is what I want and I am sure its easy and I've just overlooked it but...

When you go into a thread and you see everyones avatar, registered, location, posts, etc......I want to add in another line into that section that is customizable for each member. Where would I do that at?

Note: I do not want to change the Member title thats already above everyones avatar......I want another field where I can add some customizable text in.
