Oh dear, I have tended to keep away from forums because of the way folk just don't seem to hold the basic courtesies of communication and tend to insult others so freely.
I had hoped this would be the same but I fear not from reading several threads. This is a great shame because there is much that anyone of whatever level of knowledge and experience can learn from postings.
It is easy to write things which are uncomplimentary on these forums and which, generally, would not be said in the same manner in a face to face conversation.
A little common courtesy to each other does not go amiss and really doesn't do any harm.
We all get bees in our bonnets and sometimes fly off the handle but a little delay in typing a reply associated with some forethought and consideration really can be quite beneficial.
I hate arguments and discourtesies from whatever source - but, then, I am a white haired, white bearded old crumbly from a previous generation!
