No worries...We decided quite a long time ago that by not deleting items when they are sold...but marking them "sold" is a great way for future shoppers to comparison shop. It helps both buyers AND sellers with pricing items and comparing relative item conditions with market values.
If the thread is new enough to edit the title...then the user can do it themselves...otherwise report it, or send a PM, we can do it for you.
If you see an item that is sold, but the thread title doesn't reflect that...report it and we'll get it updated.
Thanks for understanding.
