registration question answer under user name

[reformedman]

I searched in these forum with the tags:
description under user name

but found nothing.

Could someone please help me find how to do something like what I found in this picture on another site?
They ask a question in the registration page, and you are required to answer with the multiple choice.
The question and the answer then appear under the user name everytime you post something.

I really only would like the answer alone but will take the question and answer if no one knows how.

Thanks as always in advance for all vB help.

I am asking on the server side, not the client side. In other words, it is done automatically to each new registrant without the client doing anything but normal registration procedures which is answering the questions.

To reiterate, how do I set one of my registration questions for my visitors to automatically place that particular question and their answer right under their name?
