It doesn't show up in "My Listings' or "Watched Threads'. I don't see a way to show threads I've started and I already deleted my re-listing notifications.
Any ads you created in the old system won't be in My Listings or Watched Threads. Once you create a post under the new system, they'll be there and manageable just like before.
Smith and Wesson SD 9 VE pistol.
Here it is - http://www.theoutdoorstrader.com/threads/fs-smith-and-wesson-sd9-ve-9mm.853289/
Let me know when you create a new listing for it and I'll close/delete the old one.
