HowTo authors, please move your stuff to here. While you're at it, add a header like you see on HowToTemplate and check if stuff is still valid.
After http://master18.moinmo.in/ is switched to read only (likely some time after 1.9 release), we should create HowTos from the installation / server specific stuff there that is not contained on master19 wiki, but still up-to-date and useful.
