Here is what I have so far. I'm still working on the symbols to represent each of these, but that's the easy part.
First, a couple disclaimers:
Keep in mind that the symbols are intended to be used either alone or together, so although a particular sign may seem unnecessary, it could be useful when combined with another. For example, using the sign for "go this way" followed by the "boat" sign.
Also, I may end up consolidating some that are needlessly complicated, like the ones for acceptable currency. Rather than have separate ones for each kind of currency accepted, you would simply use the sign for the thing itself (gold for example) and add a small sign next to it.
Finally, remember that this is a very rough list and is a work in progress.
Look these over and let me know if you think anything should be added, modified or omitted.
