I apologise. And I will explain.
I was recently persuaded by another member to join this Forum. I have not done so in the past for the reasons I stated above.

I am a depressive. After a particularly bad day yesterday I decided to look at a subject which I thought would interest me. I found the tone of some of the "discussion" a little more than robust; that has been my previous experience here too. That, on top of my day, tipped the balance for me.
Those of you who know me will know that I am not the miserable git that I appeared to be in my previous post.

I have no wish to detract from the discussion about Doc's sterling work. Therefore if it is possible, after a few days I will delete these posts as if I had never been here, and I will confine my future visits, if there are any, to reading but not participating in the Forum. For now.

I'm sure I heard someone say "Good!" just then ;-)
