Hi Jasmin,
I sent you an e-mail earlier about the workflow for patches in svn, but let me also say welcome to the mojoPortal Design Team!
I hereby appoint you Team Leader!
Feel free to email me if I can help you in any way in getting things moving. I'm not good at making things pretty but I do have a pretty good knowledge of html and css. I've been trying to learn more how to do things with css. I know a lot can be done using divs or spans and positioning instead of tables and currently we have mostly a table driven layout approach, so I am totally open to some major re-arrangement if needed to make things more flexible.
I know that mojoPortal can be made much prettier and I am grateful for the help from people who can make it happen.
Joe
