I just tried to fire up my GSiteCrawler program to update one of my Google Sitemaps and was informed via dialog box that my copy is only good until today, and I should go to http://johannesmueller.com/gs to download the current version. That URL redirects to http://gsitecrawler.com, which is now an empty page.
GSiteCrawler was an excellent, easy to use tool, and now it is gone. Whatever will I do. I guess it’s back to the Google Python program for now.
