Per Arkov's request (Being, he asked me to post the suggestion instead of just a PM on IRC :P).

A command via the self-tell system, allowing the user to make emotes in stealth mode, which would only be visible to those who can detect the character in stealth mode.

This would allow those stealthy types the ability to emote without accidentally betraying their presence to all the people who shouldn't be aware of what's going on.

Nifty, I am totally in love with Arkov's script. It's one of the best things I've ever seen. Brilliant.

<3, Arkov.

I believe that's how it works most of the time actually (not being able to hear a stealthed person's emotes unless you spot/hear them).

However, it is inconsistent and seems to inconsistently factor in things like being in the same party/etc.

Stealth in NWN can be mysterious at times.
