To read the AIC I have to know it exists and where to find it. The NPPL site is not a place where one expects to find news - indeed, it isn't very good at providing the basic information about the NPPL itself.
Why didn't the CAA just promulgate the people who have the licence? There can't be that many that a mailshot would be prohibitive. Other organisations send me information by email. It's my responsibilty to keep them informed if I change. Seems to work ok.
As for the changes - the rolling validity seems to be rather a good idea to me. I won't be switching till I have to on 30th June 2009.
