in reply to CB aliases
Nothing personal, but I don't like this idea (and I didn't vote you down for it either!)
Seriously, this should be a chatterbox client function, not a change to the chatterbox code. There have been plenty of nodes in the past suggesting adding such features as bad commands not being accepted, etc. None have been well received. In fact, for a while, you couldn't /msh. It was changed back (for two reasons. Popular demand, and also some heavy breakage in other parts of the CB code as a result of it).
Things like this change the personality of the monastery. Some of the best fun is watching people /msh people with amusing comments. If you're that concerned about typos like that, use a tool to fix it, not change the basic look'n'feel of the place. I had that problem (badly), by the way, but I fixed it on my end.
