Hi there,
You don't have to wait, simply give your guide a ring via email or MS and they sort out the rest. In a couple of days the papers arrive by DHL for you to sign, if the points are available and when they have them back you can make ressies with them.
Remember to be smart when adding on if you buy just before your use year you will get 2007 points but very little dues to pay for these new points as it is done on a pro rata basis.
