I've developed an online application that allows you to keep track of all of your link exchanges easily. It checks to ensure if your links are still active on your exchange sites and it also shows you the site's current PR. I developed this because I was having a hard time keep track of everything in Excel. It's a free service, so if anyone is looking for something like this, you can use it at http://www.linkexchangetracker.com Enjoy!
Nice lol. I built my own similar thing last year that does the same thing but kept it on my localhost for some reason. Nice job publishing an effective tool
