Expository OP on propositional logic?

I’m new to TPF. Apologies if this is the wrong category.

I’ve been working for some time on a system of propositional logic melding classical 2-valued logic with S5. It’s finally coming together.

Now I have the problem of how to publish, since I’ve been outside academia for almost 50 years. A TPF post would need to be rather long and have several parts.

Is this sort of post appropriate here? Should I put it on a website and announce it here? Cross my fingers and send it to JSL? Any & all comments or suggestions are very welcome!
