I suggested something like this a while back at Be Creative, I doubt even vroom could've found it now(20,000 nodes later%^).

Anyway, letting users upload their own css files, good idea.
Making a big fat form for monks to edit, bad idea.
Like i suggested in Be Creative, just allow monks to link to some css stylesheet, or just the one they uploaded, but don't go further than that. This should be considered a perk, perhaps for level 4.
