Hi, I sent out beta test keys to everyone who signed up before June 14th. The emails tend to go to the spam or promotions folder which is kind of annoying. But if you search your inbox for "Lo-Fi Room" you should be able to find in there it somewhere~
I will send out some more keys to people who signed up later, this week I think. So if you don't have a key yet, you should have one around the end of the week. But again you'll have to search for it.
