How to add a hidden link in Thesis ?

As the title goes, I would like to add a hidden link on the index page. I'm not too familiar with this theme nor too familiar in coding in general.
Any clue would be much appreciate!
TIA!

You should just toss it in the footer file. Depending on how stealth you want to be you can either hide it with javascript, css, or server side ip / bot detection. You could also utilize a combination of all the above.

Though, if you're not good with code, I wouldn't bother even attempting as you'll likely just get caught without using advance level tricks.

I just purchased the newest release of THESIS and am having such a damn hard time setting it up the way I want it, that I've given up on it ans tossed it in the trash bin.

sorry for this stupid question what is THESIS actually? Wordpress theme?
