But Merge Tags gives me
Are there really 1976 deleted questions with the [activity] tag on them, and if so, how do I verify that, so that I know this is working correctly? Do the deleted questions also get retagged? Do they really have to be retagged if they're already deleted?
I don't really have a good solution for this. The retagging could use some better filtering options, but I have no idea what those would look like. Having the ability to filter the merge on another tag (in this case the [android] tag) comes to mind, but I don't know if that would be commonly useful or if it only applies to this particular situation.
Retagging 200 questions manually seems like a real pain.
