web pages technical/"philosophical" aspects of mailing lists

[Carlos Garcia]

Hi,
        I'm looking for as many as possible good pages on
        administering mailing lists. 'philosophicals' as well
        as technical aspects. You know, it's hard to find
        what you what in usual searching engines when your
        keywords are "mailing list" and "administering".

Thanks in advance.

Salud,
                                Carlos
