Werner,
You've done a fantastic job starting it, producing it, and updating it each year and we are all enormously grateful for that. But I think that it is better - and still more relevant - than you think.
When a mate of mine who has been going for over 30 years downloaded and read it for the first time this year after sending him the link, he was blown away by it. The simple reason was that, apart from its accuracy and obvious effort to inform everyone, he didn't have to go to multiple places to find what he needed - everything was there in one place - the history, the tech regs (importantly, what they mean in real terms), the entries and teams, where to go, what to see, where to stay and so on - but most importantly, in one place....
So perhaps we need to review/update selected portions, how it is published etc, but perhaps a review and a re-birth rather than a full stop finish?
