Just to let you know, we have implemented a duplicate check on the submission form. This will tell the submitter if the title of the item entered matches something already in the database. We hope to cut down on duplicates with this. Please let us know if you see any problems or any areas for improvement!
We have also built a merge feature. This is admin only at this time. We are starting to merge duplicates on Gearogs, and will look at the other databases in time. If you see a duplicate, please mark it as [DUPLICATE] at the END of the shop name, so we can search and find it. Again, please let us know if you see any problems come up.
