Our lists are all archived and searchable at gmane.org and
I don't have any experience with gmane except for receiving
some google alerts that are triggered by new messages arriving there.
This list is searchable but not directly. "png-mng-implement"
isn't found; gmane calls it "comp.graphics.png.devel";
once you know to put that in the search form it's easy.
See for example
(also ".announce" and ".general")
They have the sourceforge lists going back to January 2007. The
godzilla and swrinde archives, 1996-2004, are at
and are plain text files. I simply use "grep" on those.
