Nod doesnt work as an emote.

Nods does..

But it pumps the left arm twice before nodding, is this by design? Looks like he's about to go into a dance :)

I've noticed this as well. I found it so irritating I started using *nods * instead of *nods*... then switched it off altogether.

Use the 'spasm' emote to dance. It looks awesome.

never knew that was an emote may have to try spasam at some point

Unfortunately, it's the only emote ending in -asm that is currently supported. :( This is a known issue.

I think its more a case of not wanting to make characters jitter about like morons for the ooc sake of it, which is how that emote gets used more often than not.

At popular demand, it will now recognize "nod" as well as "nods".

As for the particular actions -- fixing that is extremely low priority. Right now it does:

AssignCommand(oPC, ActionPlayAnimation(ANIMATION_LOOPING_GET_MID, 1.0, 0.15f));
DelayCommand(0.15f, AssignCommand(oPC, PlayAnimation(ANIMATION_LOOPING_GET_MID, 1.0, 0.15f)));
DelayCommand(0.30f, AssignCommand(oPC, PlayAnimation(ANIMATION_LOOPING_LISTEN, 1.0, 0.25f)));
DelayCommand(0.55f, AssignCommand(oPC, PlayAnimation(ANIMATION_LOOPING_GET_MID, 1.0, 0.25f)));
DelayCommand(0.80f, AssignCommand(oPC, PlayAnimation(ANIMATION_LOOPING_LISTEN, 1.0, 0.25f)));
