This is a small thing to spot - and maybe not the easiest - but when it's between two Whovians, it's a fact that's somewhat pretty hard to miss. The email address. Receiving an email from 'thelordoftime63@gmail.com' looks questionable to a non-Whovian but to a fan of Doctor Who, this unknown email participant may have just become a new friend for life. See, Doctor Who has the power to bring people together.
