Is it possible to block a user?
I have gotten two answers from the same person. Each turned out to be a wild goose chase, although he answers as though he knows the answer will work. Now he has replied to a third question with a comment that says it is the same question I asked before (it isn't), and that he answered the previous question (he didn't really). He is asking me to explain myself.
I would prefer that he not attempt to answer my questions. I do not want to take him to task in the public comments section. Is there anything I can do? Grin and bear it?
