I did a website interview and want to put the link onto my profile how can I do this please?

The related news section is drawn from a select list of sites and you can't add to the section, it is automatically filled when your name comes up in a piece from one of those sites.

You'll have to add them to the misc links section:

But feel free to also start a thread on your message board where you can drop links in to interviews you've done:
