Thanks for the entry. I like the fact that it looks a little "retro", although the S is a little hard to make out at first. Maybe just a little more background, just enough to see it start to curve above, in the middle, and below, would do the trick.
Thanks for the update, but I don't think this concept is going to make it. Some of the other ideas have a pretty cool symbol as part of the logo. I would be happy to see any other ideas you have. Thanks again.
