First of all, thank you for setting up the collection features on brickset. It's a great resource!
I use the notes section to hold the location (in the form of a box number) of my sets. It is a readily available field in the “mybrickset” android app that I use to enter my data.
On occasion, I redo my collection because I move a lot of sets around from one box to another. When I delete the collection on brickset.com everything in the collection disappears but the notes are still associated with the sets when I renter them from the database. When I look up a set I previously had in my collection, even though I don't have one, the notes still exist for the set.
Is there a way to delete all the notes?
