I'm not aware of any need to inform anyone if you are just a group of friends planning on doing a ride. After all you are just legal traffic using a public highway. There have been plenty of forum rides with way more then 15 people.
If it's an organised event with lots of participants then things may be different. I'm sure someone will be able to come up with the facts if this is so.
