Feature request: I sometimes need to write longish pieces offline for a wiki. It would be really nice if I could make sure the formatting is okay *before* uploading.
Seems like this might be relatively simple to do, at least in a basic form. Lots of people use MediaWiki with the default monobook.css. An early version could allow previewing just for that case. Alternatively, there could be a function like in ScribeFire, where it goes to one's site, creates a preview by making a temporary post, and then deletes it.
