This does not seem in keeping with your proposed intent, to do bold edits that would be contentious in the actual article. I assumed we would look at those bold edits and discuss first, but if this is actually a way for Quackguru, who has been prohibited from making contentious edits, to have edits made by proxy, then I suggest scrapping the sandbox. What is the purpose of the sandbox if you are just putting QG's edits into the actual article right away? Just edit the main article.
