Nano old boot loader sticky please

Can somebody please create/add a sticky in the appropriate section(s) regarding the use of the 'old boot loader'.

I think it's a good idea.

This is the best existing thread:

The explanation of the solution is not as clear as it could be. Then there is the bad advice given to downgrade to the previous Arduino AVR Boards version and some people seem to read that reply more clearly than the correct solution given in the original post. Well, you can lead a horse to water... So I don't know if it would be better to create a new thread for the sticky that's more clear. I'd be happy to create one if that's the direction you want to go.
