Hi Danny, I can understand the confusion, what you need to do is post a thread here:
http://www.subsim.com/radioroom/forumdisplay.php?f=219
Mainly for the pacific (Fleet Boats), if you are interested in the Atlantic (U-Boats) then here:

Both links are for SHIV, hope this helps, btw,
welcome aboard.
