For me, CHA score doesn't involve physical attractiveness. My character Myrrha De'loran (some of you may have spotted her wandering around in Hlint) is a sorcerer, with 18 CHA - and she is half-blind. You'd see it in her biography. In RPing, I equate CHA with 'interesting' or 'provoking interest' in other people. In other words, not boring. I make an effort to have lively conversations (not sure if it's working, or I'm babblng though!), interact with others on a very social basis, mingle a lot, provide intelligent opinions, etc etc. Of course, blindness is a good conversation factor... I hope I don't overdo it though.
I don't think CHA should be used to measure attractiveness alone, otherwise all of us sorcerers with physical deformities would be out of our jobs.
