According to this PCWorld staff blog post, Opera is offering free registration codes for its browser as part of its tenth anniversary up until midnight today (August 31). Just visit this Opera page, type in your email address, and then copy/paste the generated registration codes.

At the moment, my “John’s Choice” in the web browser area is Mozilla Firefox, but access to this free no-ads version could give me a chance to try out and possibly review the Opera browser.
