[csw-maintainers] Our mailing list footer

[Maciej (Matchek) Blizinski]

Our mailing list footer has been recently changed and now looks like this:
_______________________________________________
maintainers mailing list
maintainers at lists.opencsw.org

This mailing lists archive is PUBLIC.

Two issues:
1. There's an apostrophe missing in one of the words.
2. Somebody's capslock must've been jammed. Please fix.
