If you register with a username like "123-489-zrw" or something that isn't readable, you won't be approved.
If your email is something strange that I don't recognize, you're not approved. Gmail and Yahoo or MSN is good. Hushmail, Protonmail, those are all fine. What the heck is "ae2.com" for example? No idea. Nope.
So use something like "Fred1982" and register with a Yahoo email or something. That's great!
