Well, I just paid last month's rent about a week ago and it's still a mystery where this month's rent is going to come from, but if you'd like I can take the stock script that I used today (the latest version from the site AFAIK), do the "usual fixes" and insert the new linkcheck_main & linkcheck_top, and send it to you. At this point it wouldn't take me very long.

I also think it would be an ok idea to add some comment lines in a few places so people can find certain code insertion points more easily.
