Quoting from a message

[cantoramy]

Hi.  I am presenting at Nimbus-2003 and have see a post on HP4GU 
that was so well written that I asked the author if I may quote him 
in my paper.  He said yes, so now I need to know how to put my 
source in the footnotes.  Do I give the number and date of the 
message plus his name and the name of the group?  Since it is a 
members-only group, should I state that too?  Anyone else have this 
problem before?  Help!
