It's simple, go on the VS forum, and ask a question about Shipsim. And see how they react to that.
But seriously. We can't answer a lot of the VS questions here, as we're not the VS forum.
Sure, some easy questions can be answered as a lot of people here probably have VS too.
I personally don't mind general questions, but I frown upon VS screenshot or video galleries. They simply don't belong here and neither do bigger question, mostly of a technical nature, for example.
For me, I'd say it's mostly the rude behaviour I experienced on their forum agaist all things SS, that makes me think/say: "let's shut down most of the irrelevant VS content here, as it is not about SS". But again, I can only speak for myself.
And you can of course visit their main website without an email adress, and there's probably enough info to answer that question you had right there on their site aswell. I mean, that IS where you buy the game from, so in the case of "does it come in a disk version", the answer should be there. If there was no mention of it, it doesn't!
You didn't have to go through the trouble of making an account, or asking here, even, if you had just gone to their products page and had noticed the lack (or presence) of a disc version. I mean, if it's not mentioned in the "how to buy" part of an official site, it's probably safe to say it doesn't exsist.
But that's just my 2 cents..
