I’ve given a key to all accounts that were registered before August 1st, 2015. 4449 in total. If you have a key, it can be found on your account page.
Each key is a 2 use one, so those that get one can also share it with someone else to grant them early access to the main server as well.
I’ll be sending an email out to all those that got one as well later today or tomorrow to confirm for those that got one. But you can just check your account if you think you registered before then and it’ll be there if you had.
Also I fixed an issue where the main server would be missing resources the client needs to fetch whenever the test server is down, and did some various other things that just make deploying updates branched off from the test server easier and more painless for me.
