I thought I add
If you plan on updating a route created by someone else, make sure that you obtain the authors permission first. Also keep in mind that not all authors can be contacted as I did have an updated version of NormP's Brisbane South TRS 04 and Gold Coast TRS 04 routes merged and I cannot share or distribute the route since NormP has passed away a few years back, I did ask N3V Games if it was possible to re-release NormP's route as a tribute but unfortunately, N3V Games cannot provide that permission unless I was able to obtain permission from NormP's family. In the end, I decided to delete the updated route
Also some route builders who has uploaded some really good routes on the DLS aren't even on the forums.
