Looks like it isn't a scam as I thought first when I read it earlier today. Opera is definitely giving away their Opera 8 for PC for free to celebrate 10 years of Opera! 8O
Simply download Opera now and submit your E-Mail address to Opera - that's it and you should receive your key from them!
According to download.com this is a one day only promotion so hurry up since this is the easiest way to get get an ad-free Opera Browser 8 version from Opera. This offer is valid from 12 a.m. Tuesday, August 30 to 12 a.m. Wednesday, August 31 2005 (PDT).
