I got impatient after waiting a little more than two weeks for the token to arrive, so I phoned up SE and asked if there'd been a problem somewhere.
For anyone who hasn't got their token yet (I'm in the UK), they made a typo in the description and meant 14 *business days* - the token should arrive this week. They also said to ring them up if it didn't arrive by Wednesday next week.
I had a glance through the forum to see if anyone else posted this - if I've replicated a topic would a moderator just delete this one please, thanks :)
