My @Opera 11 extension "BugMeNot" was just included in Softpedia :D
"BugMeNot" has been tested in the Softpedia labs using several industry-leading security solutions and found to be completely clean of adware/spyware components. We are impressed with the quality of your product and encourage you to keep these high standards in the future.
How nice of them :)
