Re-Visiting Etiquette from Wayne Whitesides

Here is an interesting read that Wayne Whitesides wrote just a few years ago about rider etiquette and some to do's and not to do's. It's always good for everyone to be reminded of these things to get everyone on the same page. The only thing I'd like to add is the following:
8. Don't swing up from second wheel: One thing that we teach all of our beginners is to look over your shoulder before you swing off the front of the group. While our first riders in each group have been doing that, if the second rider blindly follows the first rider up the banking, have they then not made sure that it's clear from them to move up the track? At the very least the second rider should pass the first rider underneath and then move up the track once they've done their shoulder check to make sure all is clear. This will help our groups have a smoother flow, especially for riders that may be catching onto the back of a group that had a small gap.
