We know that giving your community a unique look is an absolute priority. We built the Layout Editor in SocialEngine 4 to make this easy. Still, we're getting a lot of questions about how this can be done, so we wrote a tutorial to help guide anyone with questions about it. I hope this helps a bit! We'll continue to find ways to help you make your social network stand out from the cookie-cutter crowd out there.
If you guys have questions about this, feel free to comment and help each other out! John and I are now going to turn our attention to developing the payment/subscription features in SE 4.1.
