Hi Sage, The test server seems to be an alpha or beta testing environment. I do lots of alpha and beta testing, and one thing you want is for the process for setting up accounts, is to be the same as on the final production version. The account setup page uses logic to validate an email is used for the username and this is not uncommon. Is it technically possible to use a username other than an email account, yes but since the pro version will use an email address, it's best to use the same logic to test. My feedback is only general comments about testing best practices and not directly on the 3dx test environment. The 3dx developers will have to give you a final answer. Have fun and don't sweat the little things. Oh, and it's all little things.
