Sorry if you already answered this in the application and I didn't see it, but what is the difference between primary hints and subhints?
Also, I should point out that you're going to have to remove most (or maybe all) of your formatting when you submit your proposal in Melange. I would just try to make it look as good as possible in Melange, and provide a link to the wiki so people can read it there.
