I am wanting to start a blog mainly for friends and family to read so I can keep them updated on my travels and anything else of interest. This would then likely be continued during my basic training and onwards if I have the time. My concern is inadvertently posting something I shouldn't, especially after training whilst deployed. I assume there are rules and guidelines with what you can say and when you can say it, are these available publicly anywhere? (I've read the key points on the PERSEC thread) The same with pictures and videos too, I've seen loads of pictures on facebook pages of people in different places on ships/with weapons and videos on youtube of missile launches which I assume must be ok to post? Then there's issues of PERSEC too and it's all making me wonder if it would be worth the hassle, I've had a quick google and haven't found any blogs by sailors.
