If you add your site to "Sites in Action" Resource Center at 4homepages.de, better use a hotmail, yahoo, etc. for the email address.
I added my site in February . . . and used an email address I don't normally use on the web. I have guarded that address jealously, and never gotten even one spam in it until this week, when I got a spam with references to 4homepages.de
If you have a clean email address, don't use it here . . .
