Hi, I've made a symlink "testing" pointing to woody, in http://www.debian.org/releases/ directory. Additionally I've set up the makefile to do it, just in case they get lost. (No need for translators to update that makefile in their trees BTW.)
We don't have a page describing sid right now, but I've kept the "unstable" symlink pointing to woody... not sure if there's any point in making a web page for sid, as it changes (and breaks) all the time.
