Please register on the Moodle bug tracker so you can file any bugs that you find and perhaps participate in discussing and fixing them.
"Bugs" not only includes software bugs with current versions of Moodle, but also new ideas, feature requests and even constructive criticism of existing features.
The beauty of open source is that anyone can participate in some way and help to create a better product for all of us to enjoy. In this project, your input is very welcome!
