If you can PM the number that would be great. I guess its a sit and wait job. I suppose they like the air of exclusivity and "we contact you, you don't contact us". Will see whether he gets an invite in the next month or so.
Funny thing is, after all this and "achieving" the criteria yada yada, he now actually feels "I have reached the level - eligible according to the criteria, Plat is good for me, might not take it anymore if offered esp for £1800". (Bet you he takes it when offered.......)
