I did share it, and I DID uncheck "private". Not sure what happened that it couldn't be seen.
I deleted it today - I'm going to rebuild it with the original hub as I switched to the new hub before making this one and my previous two (old hub)...
The '+' signs allow you to insert a waypoint between existing ones. It will automatically put a new one INLINE and MIDPOINT between existing waypoints. But, you are allowed to click and drag the new one if you need to.
