I wonder whether it would be a good idea to disallow any replies in the ChatterBox that start with ^\s*/m, but which are not /me or /msg. Instead a warning should be issued, similar to when you accidentally say the same thing twice.
This would prevent sometimes more or less private message to become embarassingly public.
I guess the code would be something like:
print "Don't know how to '/m$1', maybe you meant /me or /msg?\n"
if $line =~ m#^\s*/m(\w*)# and $1 !~ m#^(e|sg)$#;
Unless of course we all want to continue to peek into people's private conversations, then we don't need this at all ;-)
