Sounds like a very sensible idea Bob; anything to minimise the number of bugs and problems I find with MODx. Like others, I also always have the feeling that versions are released without adequate testing. There always seems to be more effort going into sexy new features than solidifying and strengthening existing but buggy features.
I have been ussing MODx since about version 0.8 or 0.9 and I have spent an inordinate amount of time over the years trying to solve problems. One reason is the release of bugs in the first place. Some are in the core, others are in extras, but they are aall part of modx so all just as important. Another reason is the quality of the documentation: it's huge, different parts of it cover different modx versions to different degrees, it's all written by different people to different qualities and standards, important examples are often omitted and linking between parts of the documentation is poor. In that department I think the open-source model becomes the too-many-cooks model if not properly regulated. And the auto-generated API docs? They can only repel new users.
The last reason is the community. I don't know why but apart from a few dedicated and tireless individuals (Susan, Bob and others) there never seems to be much help out there. Is there a paid version of modx that I don't know about where help is always at hand?.... I'd gladly pay, because it would save me weeks every year.
I hate moaning, but if I don't then user feedback is not going to be accurate, is it? I like modx a lot but it just seems to have become so big and so complex and so unsupported by people or docs when you have problems that it's tiresome. Testing more thoroughly and releasing with fewer bugs would go a long way to help.
I would happily do without new features for a year or two in exchange for a massive effort on bug-fixing and doc-rewriting.
These two items alone would help to encourage new users to adopt modx.
I can be more specific if required
