Underneath the sign up with email did you click on the: already have an account sign in? Link? I was able to log in with all of the links on the page, im not sure why you are having trouble signing in once the email is verified it should be almost instant for you to be able to sign in, what browser are you using? I would like to see if i can duplicate the problem you are experiencing so i can fix whatever it might be. Also please let me know as many details as you can.
