Well, Wayne, just as people get older, build up relationsships, get married, raise children etc, I guess it's at least once in a life time, that they get theatened by HF in a completely insane way. I reckon the best thing is to say, "Ah, another pointless attempt to get me annoyed and to steal some time of my life span, so why don't I just ignore it, be happy that I'm not that low and feel sorry for such people (but not too long)." (And I definately agree with Dammy).
The real pity about HF is, that he hasn't been able to leave the Amiga to make a living elsewhere. And the Amiga market is definately not a place to earn money for a living, and so things start getting desperate.
Let him claim whatever he wants, let him threaten you, I'm not aware he has ever sued somebody. He's only shooting himself in his foot all the time.
