Hello,

I read recently, via the W3 Validator page, one of your interesting tips
named "GIF or PNG" [1]. Karl, the author, writes in it he does not knows
at the moment where the GIF patents will expire, so I went and looked on
Wikipedia to find the answer: "The equivalent patents in Europe, Japan,
and Canada, however, won't expire until June 18, June 20, and July 7,
2004 respectively" [2].

These dates are closing, so I think it would be interesting to add this
information to this page.

Cheers, and thanks again for all your work at the W3C.
