When I started hiding my email address I used a free program (which is very small and you download it to your computer) called "E_Cloaker" which asks you for the email address you want to hide and the alternate text you want to show and then produces something like '<a href="©0¬ etc etc, which you can then paste into any web page, even on rootsweb pages. For an example, go to this page - http://freepages.genealogy.rootsweb.ancestry.com/~davismcdougall/family/p00030.htm#05238 - and view the source where you will see some very long lines across the page which is the source line for the number in brackets at the start of each entry for a person on that page. No, I don't use E_Cloaker to put these lines in; I have since written the code to build these lines in my own genealogy program, but E_Cloaker would be quite suitable for including a few email addresses on a page. As for Ruth's problem in a guest book, you would have to write some javascript to accept the information the guest entered onto the page and then securely hide from prying eyes. In the guest book only show the name without the email address. The javascript should send the email address to Ruth for safe keeping and never keep it on the web site and if anyone wants to write to another guest they would have to write to Ruth first and ask for the address.

Is there something I'm not understanding here? Won't a simple robot.txt keep the spiders out?

You're joking, right? :-) No, robots.txt is an information only file and will only direct "polite" spiders. The robots which harvest email addresses ignore robots.txt. It's like putting a note on the door saying "please don't rob me" won't keep a burglar away. Charlie Dobie.
