Thanks to smokncady for the email!

You can get a free registraation code for opera, to remove the ads at
the top. Just go to: http://my.opera.com/community/party/reg.dml
and enter any email address that looks real, it then displays the
code. No need to have access to the email account. I use opera for
general browsing and love it. Now I have a legit version. : )
