A: Hello AndriaC - thank you for asking. You need a Tier 3 license, but why not go for Tier 4 for full unlimited? ;-)

You will get an email sent to you as soon as I see any Tier 3 or 4 purchase - We added this after launching, so its not part of the automated redemption process. We are here right now, but forgive us due to timezone differences if we are not sending it immediately. We usually get all MainWP licenses out within 24 hours.
