Eeh, I know. I try to keep up with emacs development but even though I
like emacs and use it daily, I'm not involved enough to keep up at the
same same rate I rebuild it ;).

I have a few bug reports I submitted myself I'd wish to work on (I still
think clicking in the scroll-margin zone is completely broken), but
coulnd't put down any time on it.

I browse through the list infrequently (sometimes ignoring it for months
