Yes, I used to use 'iff' (a hangover from having studied
maths...) but I now think that outside those fields it's
too easy for a reader to confuse it with a typo for 'if'
and so it's better avoided (by using "if" when that's OK
and expanding to "if and only if" in the odd cases where
the distinction actually matters.)
