I have a number of friends in the Reg Force who routinely mention "they‘ve seen my posts in the War Diary" - thus, I know they read this.
As to their reasons for not posting here, it‘s none of my business (since, after all, the only legal way for them to post anything here includes the proviso they NOT identify themselves as serving members of the CF. As such, any posts here would be only their PERSONAL opinions, and I have no business intruding upon the personal lives of my friends and colleagues ... since I‘m not in the CF Gestapo).
Anyway, let‘s not pick on the Regs - they‘re like any organisation: some good apples, some bad ones (and, think about how much "we" hate being tarred with the same brush ...)
