Hi,
Indeed the contact form has not been working for a few days, due to incorrect permissions of the /cgi-bin/FormMail.pl script. Thanks for pointing this out, and sorry for the inconvenience. This is now fixed and working normally.
On the IE9 issue, if a message is displayed saying that you are using IE 6 or IE 7, then that's because your browser has been set to emulate one of these versions. IE8+ is required by our website since its latest revision. We don't support IE6 since a couple of years, and no longer support IE7 either since one month or so. IE8 is the first version of IE that has a reasonably low number of bugs and an acceptable support of web standards. With IE9 working as IE9, there should be no problems at all. Please let me know otherwise and I'll fix them.
