There have been post that really stretch creditability, don't know if that was by intent
or a lack of information.
I've yet to see the word 'liar' used, but I've seen sanity questioned.
I'm not taking this OP's post south, but PM is a valid and helpful instrument-
to some of us.
Like PM's, questions to individuals which are of no concern to other members.
Some form of an 'atta boy..' carries more weight on a PM.
A PM can carry more sincerity
A PM like 'What did you mean, were you serious?'
I really dislike normal post that questions another values, intent on post,
the 'mind readers,' that tell the previous poster what he actually meant.
When a person has crossed the line, a PM at least, informs them you did
not care for their post. I don't know if this occurs or not.
It is a personal message,- Me to You, rather than the entire board,
carries much more weight with me.
PM's fits a variety of my needs, some don't care for them.
