I'm not familiar with Windows 7's browser, but the mobile version is wap, which would lead me to believe that it won't be the best user experience on your phone. I assume that the regular version of the site would actually be better.

That being said, I will take a look and see if we can allow it. The mobile site uses third party software, so we might have to wait until they push an update.

Beyond that, we are working on a non-wap mobile version of the forum that should be approporate for the windows phone 7 platform.
