I doesn't matter to the moderators one way or the other if duplicates are pointed out on a thread. If that is the practice you choose, it would be helpful if you pinged us. We would like to be notified if there is a duplicate. We don't always see all the posts, there are just too many to go through.
Not only that.. but many times, duplicates are because the newspapers TITLE with their OWN TITLES. I've found (later and to my dismay, which is why I don't post articles any longer) That I will post from say my local newspaper.. to find that another paper titled it differently.
The moderators here do an excellent job. But there are so many posts.. that I've often wondered how the heck they keep up with it all.
They have saved my bacon from severe embarrassement in the past..and I'm eternally in love with them..and greatful :o)
Until I read this thread.. I never realized "pinging" them regarding a duplicate would be helpful.
