I do hope, Girly, that my 'click here' response provided the answer you required. My apologies for the subsequent - utterly needless - hijacking of your thread. This will be my last contribution to it, I promise you.
In France, Jenky, there is an organisation known as L'Acad�mie Fran�aise...you may have heard of it. The supposed function of its members is to prescribe how the French people use their language. Sadly, perhaps, these recalcitrant creatures will persist in saying 'le weekend', 'le sandwich' and a host of other anglicisms despite that august body's abhorrence of them.
As regards myself, I have a Masters degree in English obtained over 40 years ago. Thereafter, I spent some decades teaching that subject, including at university level. I really, therefore, do not require a bunch of computer-nerds (I mean your "authority") to tell me how to use the language. Underlining is an absolutely standard method of emphasising text in English...that's why AnswerBank gives us the facility to use it...and nobody is going to tell me that I can no longer thus use it. Nobody...neither Tim Berners-Lee nor anyone else.
I've no idea why you started this debate. A lady asked a question and I answered it perfectly adequately. I shouldn't be surprised to learn that a substantial majority of AnswerBankers have never even heard of Tim Berners-Lee, never mind considering him an authority on English. Leave it at that...do.
