Something to watch for when approving edits:
Make sure that the game/accessory is not being changed so drastically that it is no longer the same item.
For example, I had an accessory in my collection. Found a duplicate entry on the board. The accessory in my collection was edited to become the Brazillian version (which the only indication of existing is a flyer, no prototype has been found for that version). The duplicate was modified to become the original item.
I removed the Brazillian version from my collection and added what used to be the duplicate.
Just a minor annoyance to be aware of.
