Anyone and everyone can download the game, create and account, and log in right now. This is solely for the purposes of us being able to say "if you don't believe our claims, log in and see for yourself!" However this is just a "guest" account without any powers of any kind. You wan walk, fly, chat, and look. If you want to actually be able to "test" as the name implies, and during our alpha phase, you'll need to be a gold level contributor, or go for bronze or silver and simply wait for those phases to begin." Gold Alpha gives you the immediate power of creation and destruction at your fingertips.
