No activation email and other issues

Two of my friends registered for the forums but didnt get any activation mail. Checked spam folders and everything but still nothing. They registered before me even, I got the mail instantly, they still have nothing. Could you check that out somehow?

We get a ton of spam accounts, so it's difficult to determine real vs. fake when approving. So they could have been deleted (as spam), or they could be pending verification email (which I can approve).

Can you post the usernames?

Thanks!
