To all:
When you sell something you've advertised on the forum classified's, please go into that ad and make a post that just says the item has been sold.
That will do two things. First, it will move the ad up to the top of the index where it can be easily found. Second, it tells me and the others that the item has been sold.
When I see the owner of the thread post that it has been sold, I then change the banner to read SOLD, and lock the thread.
If you do as MikeMcK did and make a brand new post saying that something has been sold, I have to go thru all of the threads the person has made to try to find the item so that I can change the banner and lock the thread. This takes time and if the seller has more than one item with a similar name, there's a good chance I will close the wrong one.
In this case, I think I found the right ad so I changed the banner and closed it but I had to get back to the bottom of page 2 in the index to find it.
Thanks for your help.
