I joined the earlier guise of this and it was quite good, if a bit glitchy. The concept is quite good though, it's free to use and might be a good way to get noticed. The creator, David Inestroza has just launched this whole new version and has emailed me about it. I have joined again but am yet to upload anything. I just thought I'd share it.
