You might have noticed the first part of GrandFather's reply was an easily understandable, plain English question. Hopefully we can at least give the poor, naive question asker the benefit of the doubt in his ability to read.

As for serving no purpose, I guess that depends on who the purpose is intended to serve. It may not help the original poster much, but it should help other potential responders. It's like raising a red flag for other qualified help representatives, saying, "we have seen this type of thing before, please look to your previous experience to guide you in helping this individual." Was that plain English enough for you?
