During the course of a surprise appearance at the Def Con computer hackers' conference on Friday, anti-virus software industry's flamboyant pioneer John McAfee unveiled a complaint website.

The new website unveiled by McAfee is called BrownList (www. brownlist. com/), which will give people an online platform to express their anger.

The BrownList website unfolds a forum for people to file specific complaints as well as for users to suggest solutions to the complaints voiced. The site members vote on the suggestions and then decide which kind of response might be best.

McAfee said that he has set up the website to give an opportunity to ordinary people to lodge complaints about any problem --- from government corruption to bad consumer products.

With the BrownList website carrying the motto, "It's payback time," McAfee said in a brief interview prior to announcing the website: "This taps into anger in a positive way. Instead of getting angry and shooting at somebody on the highway, or yelling at your wife, you can log onto the site."

McAfee also told Reuters that he plans to make money by offering subscription services to businesses, though he did not divulge any details.
