Did you use the entire address in the site mapper?
I just checked, and came up with six pages.
Interesting Links - CRCP - A Little History - Credentials - Areas and Counties Covered - Member NAPPS
All I did was copy the link from your signature, and paste it in the opening window of the program, and click the next button.
How weird. Today it works for me too.
Yesterday all I got was blank results.
Is there a sitemapper server that may have been down before?
By the way, is it better to name a web page .html instead of .htm? Does it work better in the search engines?
