I completely agree and that's really a pity because GO was already great when I discovered it - by accident - some years ago and it has improved significantly since then.
I'm not sure, if mschering is the only person working on it but I almost have the feeling. If so, it's understandable that he cannot maintain an active forum at the same time.
The documentation on 'readthedocs' is quite good but not sufficient to become an expert.
So not really sure what to do either
