How Do I Insert Registered Username in an HTML Link?

[Scan Cape Cod]

Hello,

First off, my apologies if this has been covered, apparently I'm not using the right words to search for my question.

I am trying to build a HTML link in a custom page that when clicked will log a registered user of my forums into a Teamspeak 3 server. So, what I need is the proper "username" syntax that will go into the HTML link that will insert the person's username when they click on the link.

I know the "TSXViewer" mod will provide this feature, but I just can't quite figure out how to get it into an HTML link of my own. Any assistance would be greatly appreciated, and again my apologies if my search missed this.

Regards.
