''This subject was discussed at length a little while ago...seek and ye shall find''.
I suppose we could say this about a lot of the topics - especially for how to put photographs on the Forum, which has been well, well discussed at length! But, the advantage of questions being repeated several times is, new members who join this Forum and who have never been involved in the 'old topic' may have fresh ideas and input. So, sometimes you know it is good to re-cycle 'older topics' without the sarcastic comments.
