Written tones of voice (was Re: YAPT: Dutch ij and ui)

Tristan wrote: "'Hate' is such a harsh word that I have no idea of what
concept it expresses. Rather than letting a perfectly useable word go to
waste, I* have re-applied it as a euphamism for something that is normally
expressed using words like 'jealous' or 'envious' but isn't quite that. It's
always clear what it means in person because it's said with a happy tone of
voice but English doesn't have written tones of voice..."

Ideas, anyone?

But I guess emoticons will do...

Cheers,
