Halo 5 beta: code with Xbox preview program

Halo 5 Guardians Early Access beta is now underway with a secret test. More importantly, there’s a way to play right now but sadly it isn’t available for most Xbox One owners – only those with access to Microsoft’s Xbox Preview Program.
The question is, did you get your free Halo 5 beta code invite by email, or are you still waiting? 
In a Tweet we found Mike Ybarra of the Xbox team.  It appears that Ybarra actually offering  new members an easier route into the elusive Xbox Preview Program so it is well worth keeping an eye on Twitter for similar openings.

I have some Xbox Preview Program codes, if anyone is interested in getting early updates and helping us make Xbox One great. Contest?

 If you have verified access to the Program, you’ll also gain entry tp Microsoft’s Preview Program forum, where you’ll be able to engage in even more secret information on the Halo 5 beta and other upcoming games.
