I already asked in September to get an svn account to be able to commit directly patches to trunk (or other branches like py3k). My query was rejected because I didn't know Python core enough (and maybe other reasons that I don't know).
I helped to fix many issues using the bug tracker. The bigger patch was the bytes filename support for Python3, accepted by Guido (after a long review ;-)).
Why an svn account instead of just using the amazing bug tracker? Just because there are not enough people to review/commit patches on the tracker and so there are more and more open issues (and so more and more lost patches) :-( I will be able to work faster using the svn.
