  - GIMPS: The Great Internet Mersenne Prime Search. Join a distributed computing experiment and mathematical research project (and a chance to win fame and money) by setting your computer up to search for world-record prime numbers using its idle cycles. (I am not affiliated with the GIMPS organizers in any way, but I vouch for the software's stability and its cooperation. It has yet to interfere with anything or slow anything down; as advertised it uses ONLY otherwise-idle CPU cycles.)
- Website Operation Related
  - Submit It. Publicise your Web page here. Automated submission to search engines. Free, lower quality service and pricey, higher quality service.
  - Free permanent URL service: Surf-To. They don't give you web space, just a url that automatically redirects to the url of your choice. So set up your web page, get a Surf-To url, point it at the web page's URL, and distribute the Surf-To URL to the search engines and people who link to your site. Then if you move your web site, just go to the Surf-To web page, log in, and re-aim your redirection to the new location.
