|Instant activation mini-FAQ:|
Gmail users (2014-04-26): check your spam folder, maybe try marking messages as not spam.. as I've never spammed, so not sure why but yeah.. probably temporary issue.
Activation emails are sent from email@example.com, make sure your anti-spam programs and filters accept this. I will not respond to challenge/response notifications.
Activation emails go out instantly.
If you do not receive your activation email, you can have it resent, or change your email address by attempting to login to your inactive account.
