Thanks Phil for bringing this issue up, it would have been a problem if nothing had been in the hopper, but as Ryan said, it is. Now that the users base is widening beyond early adopters and ex-etomite users, we need to manage the image of MODx and one of the things involved is a visual identity.
On the member list, you can see there are three people officially involved with this area of the project, notice I am the latest addition (registered early november just like you). As for helping with Marketing, we’ll most definitely need all insightful input we can get ! I’ll gladly share ideas with you via IM or email, when I get the chance

. But the person who is reponsible for the marketting can drop me a line if they need help with anything. I’m a designer (a bit of a CSS guru, if I may be bold 
) who knows quite a bit of PHP and Flash. I also work in the SEO industry, so I’ve caught quite a bit of that too.
