Thanks for posting that.   Unfortunately those that need it most likely won't even  bother to read it.    And I can understand that if it is a difficult   subject to grapple with.    It  appears mostly only those that can spell and use grammar have any real appreciation of it's importance.

I read recently that over 90% of subscribers to Pinterest are women.   An interesting fact.     
 I only recently heard of Pinterest and  still havent bothered to check it out, and that is probably because I am not a woman!

But Facebook has little appeal to me  also.
