When RP'ing or just emoting in general in Istaria, I tend to swap up /em and /me. Most other games out there and most chat systems use /me for emotes, so I'm very used to that. It's a pain having to go back through all of your post that you just typed or retype it just to fix that you wrote /em instead of /me.
A workaround IS possible, and that's typing "/alias me em" which makes it so that /me works like /em. But /alias isn't a very well-known command and "streamlining" Istaria to work with other MMOs' defaults is probably a good idea. (Adjusting the default hotkeys a bit back was done for that, wasn't it?)
Just a pretty low-priority suggestion here.
