How many British-English speakers are tired of the 'American' spell check on YA?
On the URL at the top of the screen, where it says answers.yahoo.com.....(etc.), type in 'uk'. before 'answers' so it looks like:
and then your spell check will work and 'colour' won't show up as wrong on Spell Check. Also, on the left side of the page about halfway down, you can choose between All English Language questions or U.K. and Ireland only.
Not bad for a Yank, eh? NOW can we be friends?
Personally, if someone spells 'colour' or 'neighbour' or 'about' (okay, that one we agree on (lol)) I know what they're talking about. To argue over a letter seems as pointless to me as it does to you. Sometimes I spell them the American way, sometimes the British way. It keeps people guessing.
