Craig,

you are totally right. Where to draw the line is always difficult. It's always a question of individual interpretation. What makes someone angry, what not. And I guess, that an automatic banning of abreviations will not work, finally. We often underestimate the 'degrees of freedom' which govern so simple looking situations...

But, nevertheless, there is always the 'freedom' of an individual response! To say 'NO', if the indivually drawn line is overranged. So, it will finally depend on what the demogratic majority of forum contributors agrees, I assume...

Have a nice weekend,
Kai
