how the heck do you use a emote?

im no sure this goes here (could be wrong) but you type "/em" (no quotation marks) and anything you write after that will appear at his head.

Only goes for multiplayer, mind you. In singleplayer, it's somewhat complicated, as you have to manually open the replay file and add the emote at a given frame. I'm pretty sure that there is a tutorial about it somewhere in the Tutorials section.
I'm not even sure where this admittedly bad thread goes, so it'll live for now.
