authorization email never showed up

I'm having trouble signing up (emails is invalid) but I seemed to be able to "Upgrade to Full account" once I did a one-time post. However, the authorization email never showed up (I checked my Spam folder) to confirm the email address. Also, I've put in a couple of one-time post bug reports and never got an email yet.

Also, is it intended functionality to be able to start a new topic with a one-time post but not be able to reply to a current thread one via a one-time post? If not for this limitation I might have just added on to one of the following threads:
