Soon, we will be making some minor changes to the site that will not be compatible with IE6. The new changes are simply cosmetic, and the site should still function in IE6. However, officially we will no longer support this browser, and we will no longer test site functionality in IE6.
There are other options available. If you like using Internet Explorer, I suggest you try upgrading to a newer version, Microsoft will have links on their site for these.
I believe that some older versions of Windows (Windows 2000, for instance) will not support any version of IE after IE6. In that case, I'd suggest looking into another browser option, like Firefox or Google Chrome.
If you have any questions about this, please post them to this thread so other members can benefit from having the information posted in a public place.
