Scratch

Hi everyone!  I'm a high school / community college teacher in Arlington, Virginia.  I'm new to Scratch, but both my students and I are already luvin it!

Since I believe deeply in Software Freedom, I want to run Scratch on a Free Software platform (we are using Ubuntu GNU/Linux).  I'm also active in the Edubuntu community, and when I asked what I could do to help make Scratch work better on Ubuntu (sound doesn't currently work, nor image morphing), they said I should make contact with the folks working on the Linux installer and put them in touch with the relevant Ubuntu developers.  Any help doing that would be *greatly* appreciated.  My email is jeff@elkner.net.  Thanks!
