I proposed "a command or dynamic help file" because they're passive rather than active - you just access them if/when you need them, and can follow or ignore the suggestions as you see fit. It's less intrusive, it's there's when you need it but doesn't force you to jump through any hoops.

However the important part is that the suggestions are context sensitive, so if it were done with a help file it would need to be dynamic. Relatively few muds support dynamic help files, and even those that do may find it preferable to use a command.

Almost all muds have a "who" command. I'd like to see more offering a "what" command as well
