tobster: i've got nothing to really go on other than my own experience... you rush around trying to get paperwork sorted and emailed over, but then they only clear out the email box every few days. (Unless they changed things recently)
Same with posting things - one guy i spoke to said that if i posted something on a Thursday it would get there on the Friday then sit in a pile for 'matching' until the middle of the next week.
But yes, the licence does come in a holder
