Seeing this discussed in the park earlier made me think of a related client-side option of adding an alias command, that could be entirely implemented browser-side (at first anyway). It would potentially let people do things like alias ; = ooc or alias yell = pose yells out,. With a little bit of advanced magic, the last one could even become alias yell = pose yells out, "$" and allow the parameter to yell then be encapsulated in quotes, for example.
Thoughts? (Especially @Accipiter )
