This message is for the benefit of Opera users, unaware of one of it's default settings.
By default, Opera is set to falsely identify itself as Internet Explorer. This is known
as "useragent spoofing", and tricks those websites that (foolishly) block non-IE
browsers, such Opera, Mozilla and Netscape into letting you view the site.
Useragent spoofing is bad, as it potentially causes inaccurate browser statistics,
and persuades the dumbest of web developers to write their pages for IE users
only, with IE specific, non-standard code. This is bad for the web, as it unnece-
ssarily helps boost the already oversized and undeserved web browser market
share that Microsoft currently has, mainly thanks to bundling IE with Windows.
Please do the web a favour, and reset your browser useragent string to show up
as Opera. To do this, you need to go to the File menu, select "Quick Preferences",
then click on "Identify as Opera". Your browser will then truthfully identify itself
to webservers as Opera, rather than telling fibs, and identifying itself as MSIE.
NOTE added 1st August 2005:
As of version 8.02, Opera no longer spoofs it's default UA as Internet Explorer.
