Hi, Tom, Dick, Harry and any other friend,
May I suggest that to reduce the potential for confusion - where mails respond to a particular
individual, that the author indicates who they are referring to:
There are several mails doing the round starting with "Dear Peter" or a similar start point!
 I have no personal worry about being confused with others having the same first name as myself -
but as responses increase, it may be confusing who is responding to who, without backtracking.
Esp. as their mails tend to be more pertinent than my efforts!!
Regards and Ta!
Peter, Pedro and Pierre.
