HD
I am employed by my client, to advise you that the initials HD are owned under copyright by a venerable gentleman who is also know by a similar name to the one you have purloined.
My client also advises that you have virtually copied his Pprune name, which is also copyrighted until 2035, (the same age as my client).
Desist from appearing under this guise on Pprune forthwith, or we'll send the boys round.
Now naff off.....
