There is another way of making sure your personal message is not seen on site and it is called Email. I am still of the oppinion that PM's are another way of back stabbing fellow members and never been in favour of them myself. Always thought that belonging to a site like this was supposed to be similar to being on board and everyone shared their views with everyone else so that there was no ganging up on one particular member without them knowing about it and being able to defend themselves.
That's the way the mop flops.
My thanks to Brian for this site.
