How to Participate:
To participate in the public test, you must have a Diablo III game license attached your Battle.net account that's in good standing (i.e. it hasn't been suspended or banned). While the 1.0.5 PTR will only be in available in English, French, German, and Korean languages, accounts from all regions are eligible to participate.
You will also need to create a PTR account by logging in to your Battle.net Account Management page. We will be enabling PTR account creation soon (we'll provide an update once it's available), and once it's up you'll simply need to select your Diablo III game license and then click "Create a PTR account." After you've created your account, you'll be able to download the client from the Diablo III landing page, or from your Games Download page in Account Management.
