i got something. next to the usernames there is a white/blue icon with a black lightning-looking thing indicating that a user is/isn't online. the same icons are used for indicating whether a forum has or doesnt have new posts since your last visit. anyway, they both go smoothly with the layout, but if you're in invisible mode there is an orange-ish icon there that doesn't go with the whole color theme as nice as the white and blue ones. how about using sort of the same color that the bright orange links have?
yeah, that was very picky.
