You can contribute! Your support is welcome, and - of course - will be
really helpful. We're overloaded, there's still a lot of code to be
written (1), a lot of bugs to find (2), and a lot of enhancements / 
features / concepts to add (3). We desperately need support on these three 
fields.

If you're interested in contribution, go to download
section, read the documentation, and then, check out
current project status. In the documentation, you
will find eg. an instructions on joining our development mailing list,
contact e-mails to the authors and so on. Good luck!
