Safeware,
Yes, I am. If you would like a worldwide one, propose that as well. As for the UK only forums, service numbers are unique to individuals and would be a secure entry system.
Don't close down the Mil Aircrew thread, as Whirlygig says, many threads have interest to mil and civvy.
There is a place for a private forum for the military; as I said before the airline types are given that privilege on this site, so wouldn't it be appropriate for mil types to be afforded the same.
