If people request Kubuntu on the installation form we will try and support it. It is probably easier to use it as our "KDE distro" than Mandrake etc due to shared packages. However, unless people specifically ask, due to the overwhelming experience and support with GNOME that most of the "senior" WLUG members have, plain Ubuntu it will be. It's great. You should try it.
It's worth mentioning how much of a bother having to support n distros is. Last year we picked Fedora Core as our distro, but of course people turned up and wanted Mandrake 9 or 10, or Debian, or whatever else. It significantly increases load on the people doing the work, it increases loading on the Internet uplink (hard to precache things when you have no idea what people might be getting), and ends up meaning people get a worse deal from it.
