The thing is, they never actually accepted any help.
In around early 2012~ I offered my help, which they declined as I was not good enough in programming(that's fine I guess, but when you have the willing to help, you could possibly do small stuff that gets no attention).
In around 2017 I offered my help again, but this time they said that until I'll learn this huge project there is no point in joining.
Well, here we are.....tbh, I lost the believe that this project will ever be released.
They should've just make it open source years ago for more people to help, get bigger community, more people, more help, etc.
