I experienced the same problem. I was logged into the forums and followed the link on this post (I think it's yours mhahn) saw the additional terms page, clicked "Continue" at the bottom and just looped on the terms page indefinitely. I'm on the latest Mac OS X 10.10 (Yosemite) beta using Safari (8.0 10600.1.22). Tried it on Chrome and while trying to replicate the issue seemed to have "fixed" it (the site now links directly in Safari as well). I think while looking at the blog page (not logged in) on Chrome and then logging in to the forums, the site must have noted my acceptance of the additional terms (I was never presented with the additional terms on Chrome and now won't show the terms again on either browser). If you have the power to reset my acceptance of the additional terms I'd be happy to do more troubleshooting if it helps.
We suggest you to post your question in the IoT forum, here is the link https://software.intel.com/en-us/forums/internet-of-things. They should provide you a more accurate response. I hope you find this helpful.
