This is becoming kind of like the sticky thread with members' bios and how you found subsim, but I've got a few hours to kill so I'll jump in.
I bought SH4 at Wal-Mart because I hadn't played a subsim since U-Boat and Wolfpack, though I had always been a big U-boat enthusiast.
What brought me here was an incredibly stupid problem; I couldn't figure out how to make my torpedoes just go straight. It didn't take long for someone to point out that I had automatic inputs enabled
I eventually moved to the GT forums once I had my hunting style as perfected(hydro-hunting and no TDC FTW

) as I could get it, and I never left. Since then, I've had the opportunity to converse with and even meet a lot of great people, and I even got to help restore the USS Cavalla.
Thanks, Neal
