What DIN?
vec is either talking hoop, which is not unusual, or is referring to an RN only DIN.
The RAF DIN is due out in Feb 2011. Dates for all 3 RAF tranches (publication of field dates, decision notification dates, exit dates, etc) have been briefed by Manning, at least they have at one location.
Basically there is nothing you can do, except some individual long term speculative planning, until Feb/Mar 2011.
