Alice 3 has a bug reporting system. It has been online for a year and a half. If you are having problems submitting bug reports, let me know. The best way to submit a report is through Alice 3's interface. You can submit a report via one or two clicks when an exception is thrown, or submit one manually via the Help menu. And, of course, through the website.

Currently not all bug reports are publicly visible, due to privacy concerns, but all reported bugs go through me.
If you have any suggested improvements for it, please do share. I am always looking to making the bug reporting system better.
I'm sorry that there is no working system for 2.0/2.2. But we are spending all of our time moving forward with 3.
