Just FYI, there is a problem with asking (and answering) questions like "Do you know where I should publish this new idea I have". And that problem is, you really should not be thinking about publishing anything at all, nor is there hardly any chance that your work is both correct and new, if you have not read through all contemporary published work. You need to know what everyone else in the field is working on NOW, not what they were doing 50 or 100 years ago. But... If you actually have read through all current work, then you would already know the current journals yourself, and wouldn't have to ask about it.
Please, do yourself (and us) a favor and ask yourself whether this applies to you.
P.S. in light of the crackpot index thread in the general forum we just started I find the first sentence in the OP hilarious.
