Thanks for the explanations. I volunteer to help as well. From working on
the docs and scikits.image I am familiar with most of NumPy/SciPy, but not
with the C internals. Please just tell me if you think more experience is
needed for this role, or if there are better candidates. Then I'll happily
work on other things.

I'm using OS X, so no problem there.

Cheers,
Ralf
