Due to my overly aggressive banning of certain web site tools from connecting to my web server, I mistakenly blocked access to W3’s validation service. I reference this service on my Browser Compatibility Page. Since I recommend adhering to web standards and the use of standard compliant browsers, I feel this service is much more valuable to my readers in helping them understand the reason for web standards. Once again, the link is valid and the service is no longer forbidden access. Even though no reader brought this to my attention, I am glad that I caught the error.
