The description of the program says "Get the latest preview builds as soon as they"re available plus access to an easy-to-use feedback app." and the link takes you to insider.microsoft.com, but the link is currently dead.
We do wonder if this feature will be tied into the "rapid release" information we exclusively reported on earlier this year where Microsoft has made it easy to upgrade builds.
While we do not know if Microsoft will release a preview build next week, the company is preparing to release a technical preview that will be available to the general population.
