In reply to Apachegirl:
If you mean Andrew Moorhouse, I think he's possibly a little bit strange, going from things posted on here and elsewhere on the web, bearing in mind not everything on the internet is reliable.
If you mean somebody else, don't have anything to do with them if you're unsure about them, it's probably worth risking being too cautious, expecially if he's not a friend of somebody whom you know and trust as a judge of people/chooser of friends.
