FYI, i've been seeing some complaints about emails not showing up or taking a long time, so in order to not hinder new sign ups, i went ahead and suspended email verification for now. I might look at turning it back on later, but for now I wanted the user on boarding experience to go better.
This means that you should, after setting up your account, add an email to it, just to make sure you have the ability to recover your account at a later date.
Definitely a wise move. In the context of everything, new users presented with too high a barrier for entry will likely turn around and go back to reddit. I tried signing up over 24 hours ago, and never received the email, I've only just been able to log in for the first time now.
