I'm listing a lot items because I am cleaning out my closet as I prepare to move. Today I received this message when trying to list an item: Attention Seller:In order to maintain a safe trading environment, selling limits are occasionally placed on accounts. At this time, you are limited in the number of items you can list (or revise) in any 7 day period. If you have any additional questions about this subject, email us at Customer Support. What is this and is there any way around it? I emailed customer support, but they probably won't answer for a day or two. I need to finish listing my items today or tomorrow. If I open a store, will that lift the limit? Any information would be helpful.
