This makes me think of that old saying, "It's easier to ask forgiveness than permission." Since the majority of the world's population is too lazy to type out explanations and requests on a regular basis. However, for those who do favor this approach I recommend a macro designed for this purpose. It should also include the command to disable NN since, honestly, if they don't want to be part of the network it's much simpler to disable it than make possibly rude "boot me" requests to players that are just trying to help with the tools they've been given.
