Free Opera registration codes

As part of Opera’s 10^th birthday celebrations, they’re giving away (for today only) free registration codes to remove the advertising from their browser. I imagine this will only work for the present version, and when a new version comes out people will be hooked, and either put up with the advertising or buy the real product: either way, they make their money.

It’s a brilliant move, and a great way to celebrate 10 years!
