A very simple proposal. Personally, as an immigrant from pure-text MUCK and IRC systems I'm very used to having the /me or "pose" chat feature available in all aspects. Even so, I was pleasently surprised to find it supported in normal chat mode. But more to my surprise, it /is not/ supported in IM chat. Just doesn't seem to make sense that it be supported in one type of chat and not another, but I tend to think too straight-forward at times.
Can this be enabled, or is there a social or technical reason that has eluded me up to this point?
