Basically, we've fought ourselves to a standstill, but luckily they've just capitulated before my next move, which was to personally visit them in Nottingham with hard-copies of the offending items!

So all seems to be well, but for future reference, my question is this:
Can I convert a document to a .PDF format if I haven't subscribed to the paid version of Adobe Acrobat?
If so, what's the easiest way to (say) covert the text of an incoming email?
