Superb. Many open source projects still bounce you to Google Groups for discussion, which is archaic at this point. Even requires Google login just to read threads. Also it's often unclear what the policy is on raising questions in the issues tracker (smaller projects are usually fine with it, bigger projects get overwhelmed and don't want it). This will make it a much nicer separation for everyone and keep the issue…
Fun fact: if your session is "expired" but the cookie says you have an account, it forces you to log in, even if the group is public. Workaround: incognito mode.
