little extras in mp JKII

[caelestis]

i find that little things such as taunting and coloring your name is pretty cool, but it seems like there are probably a lot of little things that I do not know,

so far I can just change my name color, but i dont know how to change the background color of my name, and I know how to taunt, but is there anything else?

plz list any cool little things any of you have found to do in mulitplayer..

thanks
