I was looking into my hard drive to search for a good popup program I can use for my blog. Then I came across a program called Impact Popup (widely popular due to Master Resell Rights available).
Upon research on Google I came across Joel Comm’s website which has an article on the Impact Popup program: http://www.joelcomm.com/impact_popup.html
I clicked on the Impact Popup link in the article and to my surprise the domain is not currently registered (http://www.impactpopup.us)! *bing… lightbulb moment!*
So, there you have it. You can either place nice and inform Mr. Joel Comm about this, or snatch up impactpopup.us and purchase a MRR right to Impact Popup and use the enclosed Salesletter to slap on the domain. Who knows, you may even make some sales for no promotional effort on your part!
