we have tried publisher and have got on well with it.. but when we speak to publishers and magazines they all laugh at us and say its a waste of time!!!
something to do with formats??
Fair comments really re: MS Publisher lol (at least from a professional print point of view) - but ask them what formats they
can accept - if they say just Quark, then it's your turn to start laughing

(and find someone who can actually do their job).....
Ideally, you need to know what file types they can handle, and what dpi setting and possibly what colour format.
HTH
