Day 1: We kicked off with an easy question. We wanted to know the height of Jon Stephenson von Tetzchner. Correct answer is 195 cm and our first lucky winner was Kuja IX. Congratulations to him. 
Day 2: It was time for a question about CSS. What stylesheet on opera.com is called if visitors (have to) use IE6? The stylesheet is called "ie.css" and serious was seriously spot on. Good stuff.
Day 3: We wanted to see who knew a bit about Opera's "Open the Web" project and its partners in crime. Which city in England does Opera's Chief Web Opener hail from? PientaL knew that David is from Newcastle. David Storey is an active blogger, both in his private blog and the ODIN team blog. 
Day 4: We wanted you to choose question of the day for December 5. In light of the release of Opera 10 alpha Nerak wanted to know what development build of Opera's layout engine, Presto, scores what on the Acid3 standards compliance test. Thanks to Karen we could now continue the epic contest.
Day 5: This question was brought to you by Karen and Ryan knew that this build scored 100/100 on the Acid3 test. 
Day 6: When we launched Opera 9 back in 06 we had a kick-off party in the US. We wanted to know in which city. Correct answer is Seattle (btw, check out cool photos from the event by best damn tech show and DotEd). Zarshir remembered the name and was winner of the day. Hooray! 
Day 7: Speed dial is a popular feature of the Opera browser, and we wanted to know how you could add a total of 28 speed dials instead of the default 9 in Opera. David Terei knew that you had to open speeddial.ini, add/change (if already existing) the following lines: Rows=4 Columns=7.
Day 8: Yesterday we wanted to know how to add custom Web searches in Opera (and later change its keyword). Michael knew how to do this, among many others: Go to the site you want to create a search for, right click on the search box and choose "Create search". To later change the keyword head to "Tools" -> "Preferences" -> "Search". Select the custom Web search you want to edit and give it a new keyword. Easy. 
Day 9: Today we want to know the Norwegian name for this traditional dish of dried cod soaked in a lye solution before boiled to give it a gelatinous consistency?
