With apologies to Allen, I take this chance to show just how easy it is 
to forge email.

For those interested in checking whether this is a forgery (or at last 
from a different source from the one I'm quoting), just check the headers.

The key point is that it's trivial to set an alternative identity (I'm 
using seamonkey which might be another clue I'm not Allen), but 
Thunderbird can do it too.
