This has been bothering me for some time.
Why does the logo in the top left corner lead to http://arduino.cc/ when it clearly says "Arduino Forum"? Wouldn't it be more logical to lead to Arduino Forum?
I got caught out by this too some time ago.
But I found that if you hover over the 'Arduino' you get the link for the main site, and if you hover over 'Forum' you go to the forum.
Clever eh!
Oh, cool.
I was always aiming my mouse at the infinity loops so, naturally, it didn't work as expected.
