My initial thoughts were simply that my update might not be good enough to release as this is my first "real" attempt at doing it. I`ve experimented with it before as the start of this thread shows but now at least I understand the process a little more.
If I manage to get the track updated as I`d like and it`s of a good enough standard, not causing any problems and all permissions needed have been granted then I most definitely would release it and share it with the community. I`d like to do that and give something back to the fantastic and very kind GPL community.
We`ll see how things go.
Good luck for your project.
Take your time.
