I've pre-registered for two subdomains, clicked the email, logged in to my account but I can't add them because it says they're "taken" (by me, presumably). How can I add the subdomains I reserved?
Are you using the email that you made the reservations with? We do the match on that.
Otherwise, if you want to shoot me an email at rita at cloudflare dot com, with the subdomains / email you signed up with, I can look into it.
