Some of these are great, we're going through designs each evening this week to rate them and provide feedback - we're not ignoring you!
Just FYI - I've added another clarification, vector designs which can be resized easily are a must, some of these look great, but I'm not sure I could enlarge them very much without losing quality. For those which already meet this criteria, brilliant, +50 internet points to you.
Entry #7 is a copy of this. :)
