Hi,
I have put up at
http://www.redfrontdoor.org/IFSO-letter/suggestions.html
some ideas for letterheads, based on Cathal McGinley's original LaTeX class. I haven't printed them out to see what they look like on paper, but thought I'd send them round for comments now.
Somebody mentioned that they liked "Promoting and Defending..." better than "To Promote and Defend..." so I've given that a try.
Ben.
