Well, I have to side with those wishing for a comprehensive manual in PDF format. While this forum and the scattered all over the place wiki pages help, to be honest they are a tangled mess, often confusing, hard to navigate, use, understand and can be misleading and therefore I'd guess aren't used much if at all by most especially by beginners to the application which after all is who they are mostly intended for most.
This is NOT a knock on the product itself. As I've said several times I find MC excellent, outstanding even in several ways. However that said a product is only as good as what you get out of it. People simply aren't going to invest hours hunting around wiki pages everytime they try to find out how to do something.
Same with asking questions in a forum. Again, nice, but it falls short. This sets up a sitation where more seasoned users that have been using MC for years one version after another get the benefit of all the features because through trial and error they've learned most of the feaures and program quirks while those new to the application limp along, often stumble and use MC at it miminal level, never or rarely discovering all the little extras it does have which in my view is self-defeating. Yes MC is a very good application. It would be a much better one if it had a comprehensive pdf file any application this complex screams out for.
