welcome
You can go ahead fill in this section with a welcome text or maybe a small profile. Maybe you can turn this into a headline section. Whatever you want to do with it you can. I would just like to remind you that this section does start to scroll after 86px has been filled with text or whatever you put in here. So go wild!
chatbox
You can put a chatboard here or something similar. If you do put a chatboard here, I would recommend greatly that the size is exactly 134 x 85px. That prevents the stretching and makes things remain even.
To-day we love what to-morrow we hate; to-day we seek what to-morrow we shun; to-day we desire what to-morrow we fear.
Robinson Crusoe - Daniel Defoe
