Help About Blind Links

[Zio]

Hi all

Just going through yet another submit round and so far it's going pretty well, but I received a handful of rejections motivated by "blind links".|confused|
Here's the FS: http://www.route2x.com/solo_amateur_...lla/index.html
My problem is that I have no clue how to even make a blind link, so I would like to ask if any of you can explain to me (as if I were a 3 year old) what a blind link is and what it looks like cause I'm a bit confused.
Moreover, I'm restricting my subs to LLs that have been giving the best return and, since the rejections have come from sites that have been so kind as to grant me partner status, I definitely don't want to repeat whatever mistake I made with the above FS.
Please note that I started putting in more text links to the sponsor on my FSs because I read in this great forum that these tend to give better click through rates than banners.
So please fire away and while your at it I wouldn't mind to have your opinions on the design.
Thank you and all the best!
