what grasscarp means is that if you post a question and then receive an answer, you can then thank that person within your question. That way you don't open up a separate thread.
I hope that is not as clear as mud, regards, Roger.
You post the questions and you subscribe to the thread and anyone interested in replying will also subscribe to the thread to see the replies.
Otherwise you push people off the front page.
Still at least you ask for a list and don't post singly.
There, nothing narky in this reply!
