is /emas only for gm's?

I tried using /emas @{Selected|Token_Name} in my macros but get an error message whenever I try to use it logged in as a player. I play multiple characters so /emas would be very handy.

Yeah, its gm only. :(.

That's a serious bummer

I would just like to say that /emas may currently be intended to be used as above, but its potential is greater than that.
I have entire pages of tokens in my game that I name and group by association so I can just click on the one i'm supposed to be talking/emoting as at the time and use /emas @{selected|token_name} and /say @{selected|token_name}.
being able to use this feature as a player would be tremendous - I have players that would have entire conversations with themselves between their characters and incidental NPC's, just for fun.

I agree. While each of my NPCs has /emas commands to click and emote as token name every time, I'm in the kind of game where, for example, players run two characters per combat, and we have been pretty frustrated as it is. The players would really like the character's voice to change without clicking that extra chat box button.
