Fellas, there is no need to be rude. We're all adult people with a passion for the same game, so keep it civilized.
Let me clarify the situation, so you guys can go ahead and develop something nice!
We at VSTEP very much approve the idea of user generated content. The most important rule for user generated content is that the content should be in sync with the realism of Ship Simulator 2008. As you are undoubtedly well aware, before you start developing, you should do research about ships and their fog signalisations. Like Luc rightly mentioned, most ships have only one horn and so it is not necessary to develop a new horn.
We don't want to replace the current horns and the new user created horn sounds pack by TerryRussell, as they are really very nice.
It would be very nice and an excellent addition however to develop the fog systems aboard these ships (bells, whistles, etc.) when they have one besides a standard horn, and that would add to the realism very nicely. And yes, in that case we would add an 'F' key to be used for that.
Once again, we've already got horns, but if a ship has a secondary fog alarm like a bell, whistle, or even a second dedicated fog horn besides the standard horn, it would make a nice addition to the game. It is however imperative, that before developing you make sure the fog systems you develop for a ship are in fact the real systems used. As long as it is the case, we'll be more than happy to make this fog patch available for the community and add even more realism to the Shipsim.
I hope this clears up the matter.
Kind regards,
Frank
