Legends of Equestria will be running a release schedule later in the year that allows them to slowly trickle people into the permanent beta of their game. Staggering out the release allows them to build a base of feedback and testers that are interested in improving the world through each stage.
If you want in on it, head on over to their application page. This will be primarily focused on people looking to test, so if you aren't willing to do that, save the spots for other people.
The actual L.A.R. period begins in Decedmber
You can find the full announcement over here.
Thanks to Harrison, Chicago, and everyone else for sending it!
