Is there a good guide online to what all the different icons mean that can appear next to people's names?

I quickly figured out the movie-film icon that means the player is watching a cut-scene, but there are several others I still don't recognize: a blue hexagon with a smaller movie-film symbol in the corner, a reddish icon that might possibly represent a chair, a pair of red daggers conjoined in a V shape, and possibly others that I haven't noticed or can't remember off-hand.

The same goes for icons by mobs' names, although I've at least done a somewhat better job of figuring those out on my own. At least I can recognize the blue double blob of mobs who won't aggro and the triangular icon of ones that will. I can also recognize the icons that indicate mobs in my hunting log or the great big Q of quest mobs, but again, there are a few other icons I've seen but don't know what they mean.

Anyone know of where these (or for that matter, other UI-type features) are explained?
