Welcome Bill from Washington State!

Glad to see you registered with the right websites for your Submariners Pleasures. SH4 is a grand game that I thoroughly enjoy and it calms me down after a long day. I can only guess but I take it you have not played any of the other games in the series, so I think you will enjoy the experience you are about to incur. We have our resident experts here for which can probably handle many, if not all of your questions that you may or may not ask. But I have to say that the majority of OUR experts are also the experts at SUBSIM as well, since both of these websites have many cross-memberships.
But first off, please don't feel that you may be asking a stupid question, because I have the belief that the only stupid question is the one NOT asked. But I guess you have heard that saying already. I still somewhat think of myself new to the game, even though I have been playing it for a year now. Why do I say that? Because whenever I play the game I find something new about it that I did not know before. It could be a keystroke shortcut, a mouse shortcut, when to dive and not to dive, and other simple but not known moves.
But you need some experience sailer, so let's hit the seas!
