I do nt quite follow your point about transferring something to your sandbox as a reason for undoing my edit and I have to say I find it hard to believe that an editor with 17 000 edits would be unaware of how to easily revert an edit indeed that was one way or another exactly the action you performed to the article in question It can be disappointing when you ve put work in that you were unaware ran contrary to a content policy but try not to get exasperated Again kudos on your fine contributions to Wikipedia Thanks talk
