_ works the same as " ", but _ will show up under your name.
I recommend /surname "blah blah blah", as it won't show annoying _'s under your name.
But _ work's just aswell.
What _I_ recommend, is to read the readme, if its up right now; not sure if its down since the new site is in. But last I knew the readme had all the commands in it, and put in for which status levels, really handy for new users who don't know all the commands.
Also #help works ingame, just the same
