A friend of mine has started a new website and asked that I do a little promotion, to help him get some traffic. I noticed he had some categories that were well suited for the community here ..
The site is called 'I Have the Best', and you upload video, audio and images showcasing what you have the best of. Some categories that would be suitable are 'Autonomous Robot' or 'Destructive Robot', etc. There are a lot of other fun categories, as well. He also accepts ideas for new categories.
