I have a mac that I would also like to be able to post from, and unfortunately those options are not available for mac. But I realize any program that supports metaweblog posting *should* work. I say should because I downloaded a few and the closest I've gotten is a blogging program called MarsEdit. The only hitch it seems to have right now is it wants a blogID for my metapost. Is that something metapost has? or DNNArticle? or is this software not compatible at all?

Thanks and sorry if this is a naive question, I'm quite new to metapost etc.
