I think we should look at allowing user uploads into a wiki using the exiting file management system. This will get replaced eventually (see the DMS discussion), but should always have the same API.
It would be nice if the HTML editor gave the user the same options as it does for the teacher -- that is, provide me a list of images I could select when I click on the image button. Right now, all I can do is specify a URL.
I haven't played with this level of the code yet. Would that be possible with what we have now?
