You can browse the list of listings from the "View listings" section in your admin panel. From there you can monitor the listing activity in your marketplace.
All the listings in your marketplace will appear in that section. You can find the:
- listing title
- author (and access their profile)
- date it was created
- date it was last modified
- category it belongs to
- status (open or closed)
You can also easily access the edit page if you want to update something in that listing.
Finally, you can sort the listing by creation or update date in order to easily manage them.
