AutoGRAMMAR

AutoGRAMMAR will be useful to most of us. I admit it's helpful to recognise those who cannot use a dictionary nor spellchecker. But most of those who don't bother to use spellchecker won't use AutoGrammar either, so the dim-witted, lazy and grammar accident-prone will still be identified.
 I like the reader's comment about 'get' (meaning fetch) a drink, and 'have' (meaning obtain) a  drink. I had never previously noticed that 'error'.
