If one want to get more informations from Microsoft, one way is to become a sitebuilder, level xx. In this case, a MS robot looks for the "IE" symbol on one of your pages. So it must be reachable via a link.
So, now you know, why this page exists!
A very good example what some certificates are worth.....because of this page, I became "MS Sitebuilder Level I" ....<g>
