I note an exasperating trend on this list, and on t'internet in general,
to personal reinvention of English spelling and grammar. For
instance: the Whitworth spellings for the various flavours of 'your and
you're' (as opposed to the UNF or Metric, of course) are as follows:

'You're' means 'you are', 'your' never ever means that.
'Your' is a possessive pronoun, and can only be used when you mean that
something belongs to 'you'.

Do try and get it right folks, as the grating sounds of the
crossed-threads in my brain are getting irritating.
