I found it convenient to use mechanical dumps of mailman pages in attempting to create some moderator documentation, intended primarily for local use at the university where I work.
Such dumped pages do not contain any formal copyright/left statement beyond alt="GNU's NOT Unix"
- Is there a suitable comment one could/should (should not?) add to attribute the source of such excerpts to GNU (GFDL?).
I use HTML dumps rather than screenshots so that I can modify them to create a mockup of a page which refers to a particular mailing list by name, and actually links variously to the real mailman server links, or further mockups as seems appropriate (to me).
In addition, form items such as radio buttons will tend to appear in the manner the particular browser will display them on the real page.
Adrian Pepper P.S. That's enough to start. Further analysis and tangential questions "2. and 3." exist already, perhaps in response to followups.
