Hello,
Many of the users who rant of others top posting have been guilty of worse discourtesies in the past. I remember one of the so-called 'senior' users has called someone a moron. That same user has appointed himself a custodian of netiquette.
I suspect that this ranting about top-posting is merely a pretext to keep their name appearing on the list i.e to boost their egos.
Regards Suhit Kelkar.
