Hi
jacques,
My worst two offenders are
teh => the, taht => that, in fact so bad that I have installed a programme that checks the keyboard input and automagically changes them (and many others) for me when 99.99% of the time I misspell them. It would seem I have 'learnt' to misspell them in the same way that you teach your fingers chord shapes on a guitar...
Whilst an interesting and potentially good idea I don't believe the extra strain it would put on the site would warrant such a feature. And anyway sometimes it's fun to see the typo's that people make, we're only human after all...?
