> If you see a comment you think is ridiculous click "link" and you should be able to flag them. This option isn't available to everyone - I, for one, don't have flagging privileges. I'd assume that this is probably a karma threshold, but it appears I actually have slightly more karma than you do, so they must be using some other metric.
So when you click "link", you don't actually see the "flag" link at all? With my low karma it's appearing for me. FWIW, I've never flagged anyone before.
I don't remember ever having this privilege, on either comments or on stories.
