antx16,
That was brilliant.
I have the impression that some people don't really know the value of this and want it to be something it is not.
To be honest, I don't even see a need for a macro or script unless you are going to be setting up blog farms or other oodles-of-new-sites systems. (Then they are cool.)
For us normal mortals, a person can make a txt file with your list (after removing the numbers and fixing the last one) and use the replace function in Notepad to enter his site's URL in the place of "yourdomain.com". Then all he has to do is copy/paste the finished URL's in the browser one by one. A few minutes and it is done.
I think it makes sense to do this by hand if you are doing only one or a few domains since, when I did it just now, a couple of the sites hung and some others had to have the site's URL entered into the form in order to work. (I don't know if this was a temporary glitch.) By hand you can attend to these cases easily.
If you have a hit-and-run kind of site, like that cute (but small) Google Trends/Blogger method I have seen around, quick indexing allows you a hell of a lot more flexibility. Also, for those who provide SEO services, this is a great way to impress clients.
I am seeing grand possibilities...
Thank you for some real simple high-quality I have not seen anywhere else. And I read a lot.
