Since there is often confusion on this site as to which Ubuntu derivatives are actually on topic, why not explicitly list them on the Help page? Instead of:

> We welcome questions about:

>Using and administering Ubuntu, including [official Ubuntu derivatives][1].


Something like:

> We welcome questions about:

>Using and administering Ubuntu, including [official Ubuntu flavors][1]:

>    * Edubuntu — Ubuntu for education
>    * Ubuntu GNOME — Ubuntu with the GNOME desktop environment
>    * Kubuntu — Ubuntu with the K Desktop environment
>    * Ubuntu Kylin — Ubuntu localised for China
>    * Lubuntu — Ubuntu that uses LXDE
>    * Mythbuntu — Designed for creating a home theatre PC with MythTV
>    * Ubuntu Studio — Designed for multimedia editing and creation
>    * Xubuntu — Ubuntu with the XFCE desktop environment
>    * Ubuntu Touch — Ubuntu for mobile devices

My understanding of the scope of AU is that anything not in that list is off topic. Since that is only 8 items that don't change very often, it shouldn't be too hard to maintain (he said, safe in the knowledge that maintaining it is not his job anyway).
