Just got my Subsim 2007 Submarine Almanac through the post, and looking forward to reading it. At 378 pages it looks like it will last me a while, and might even make up for the disappointment of being able to read the SH4 manual from cover to cover in about, ooh, ten minutes maybe
Incidentally, I got the Almanac courtesy of donating to subsim, which I recommend you all do: A) because you'll get that book, and B) because if you like this forum as much as I do, you ought to help old Neal out with the cost!
Go on, get your hand in your pocket.
