I cannot speak for any other ex RAF people, but when the site was pointed out to me I found the comments from current serving personnel quite enlightening. I did not want to leave but realised that the RAF was being mis-managed and reading the forums has confirmed my concerns.
Additionally a lot of the younger serving personnel/thinking about joining people/just about to leave personnel often ask for advice, it would appear that as a lot of experience is now the other side of the fence we do have something to offer.
Also there are those who seek historical information, which for those who are not old enough or have problems using Google they need the 'ex personnel' to dredge their memories and photo albums to help. Plus it is a place where we can find out about re-unions, the loss of friends and the recent sterling efforts from all to get Mr Pun VC into this country.
