Bleh. Me and my big mouth.
Yokay, it's a very good idea. There is a much better mobile theme available for smartphones for SMF 2.0 (in fact there are a couple of them) but they don't work with 1.1.x. Shouldn't be hard to make something though.
First thing is to decide what templates it should have. It would be a hell of a job to include all of them since there are forty three of them, and that's before we even get into the additional ones related to the portal/CMS.
My thinking is that we should drop admin and profile functions, as well as all the portal blocks, and just have something fairly basic that covers the forum content itself plus the search function.
Devious, treacherous, murderous, neanderthal, sub-human of the West.
