The user Josh Unger has been submitting a ton of suggested edits, where the only change is to add the
internet-explorer-7 tag to questions that mention IE7. This is being done without addressing any other concerns in the questions.
Normally when someone asks or answers a question poorly, I am able to comment and try to help them out. I am not sure how to contact this user to help them recognize that they need to do more thorough and careful edits.
So, I'm asking this question: What can be done about such a user?
