I just read a post when someone asked why his previous posts had not been answered.
One reason can simply be that the post was not understood, for example because of abbreviations. Or that someone is using expressions that are completely obvious for them but not for others.
For example some Americans here on this forum seems to use every day expressions that the rest of the world are not familiar with. Of course these posts will be ignored by two thirds of the participants.
I hope that we can help and understand each other.
