I don't think I've ever used the word forest before ('wood' would be the word I'd use) and I actually didn't know how to spell it before writing the OP, BUT both those instances of misspelled words are actually due to this ol' Chinese keyboard I'm currently using - it's way past it's sell-by date; the right shift key keeps sticking, quite often letters aren't written -or they're doubled- when I press keys... this little post has already had five of those keyboard errors (that makes six) that I then have to go and correct (seven)

ETA: and it's impossible to correct spelling in a poll once it's posted!
