[plt-scheme] PLT projects waiting for contributors?

Hi,

in a recent thread, I read Shriram Krishnamurthi's

This reminded me of something: I'm a Java developer at work and studying
scheme in my spare time (mainly by doing SICP exercises). Doing the
exercises is great to understand the theoretical stuff, but I'd like to
do "real-world" programming in a functional language, too.
Of course I was thinking of developing an own application, but recently
I realized that if I took part in a project, I'd get feedback and would
learn to write better code.
So my question is, are there any PLT projects that need contributors
(and can afford taking in people who are not so experienced yet)?
In fact something like the above - compiling for the JVM - would really
interest me, but I'd be curious for any suggestions!

Thanks in advance
Sigrid
