Choosing a "Component" for new issues really does help some of us
browse the issues.  We have components called "Unknown" and "Other" so
there should be no excuses for not choosing one.

Actually, it'd be even better if David or someone with the right karma
can look into this:

Let me know if that doesn't work and I can dig some more.
Thanks,
