The best way is to add them as patches to the sf site and then post
here with a link to the patch (and attach the patch if possible). I
tend to monitor this list much more closely, but it is nice to have it
on the sf site if it falls between the cracks because it is easier for
someone to pick it up later. If you get no action in a week or two,
ping us again.

We are trying to move away from adding our own numerical code and have
this go into numpy/scipy. I suggest adding a docstring saying,
additional window functions a,b and c are available in
somepackage.somemodule

This is fine -- I suggest using the matplotlib.cookbook.iterable
function or the python builtin callable function to do the check.
Whatever changes you make for specgram should also be ported into psd,
csd and cohere.
Thanks,
