We at Clearleft like to think that our Silverback software is already quite fantastic (easy, affordable, and gets the thumbs up from lots of happy UX folk), but for World Usability Day it’ll be getting an added bonus - 100% of the day’s sales will be going to the The Dian Fossey Gorilla Fund International. So if you haven’t already experienced the joys of simple and truly effective Silverback, buy your license this Thursday, November 11th, and send a little love to the gorillas!

And if you’re in the market for some tip top UX tools, our friends at Optimal Workshop are offering an incredible World Usability Day bundle which you can check out here. Amongst the goodies you’ll get are Silverback and a $70 donation to the Dian Fossey Gorilla Fund - it’s a real steal of a deal!
