If you are a WHS beta tester, your release candidate awaits. For those who want to jump in on the action, Microsoft has re-opened signups for the time being, so don’t waste any time. They didn’t mention what was new or fixed, but you can bet we are getting very close to RTM. If you are unsure what WHS is all about, you can read our preview from earlier this year.
The community has been chomping at the bit for RC. And while with Beta 2 and CTP we accepted applicants into the beta program in stages, we’ll make the RC software available to all 100,000+ beta program applicants asap, as well as all new sign ups.
