It seems normal policy with most (if not all) Forums for the contributors to benefit from being able to remain anonymous. Even those who operate Forums and Blogs seem to prefer this option, such as Oscar or Disgruntled from Croydon!
I just wonder how many Bri Roberts and Dave Roberts we have in the area, together with Owens, Williams, Jones and the plethora of common Welsh names. Don't think naming would work, altough it would be helpful to know sometimes.
I see no reason why the Forum Admin should not, if circumstances arose, politely ask a contributors name and retain it privately - but then I cannot see such a need arising!
As an aside, I have never met (as far as I know) Bri or Dave Roberts, don't care if I ever do meet them, but probably would enjoy it if I ever did.
