We do so because we feel that forums in which users must engage one another personally are generally warmer, more collegial and friendly. This is one of the few rigid rules that we enforce regularly.
You took the time to be here, we want to get to know you. We do this in order to keep conversations personal and familiar. Since 1997, we have asked users to sign their real name, first and last, to all posts in the PMDG forum.
