I've noticed that when I'm signed into c9 everything is displayed left aligned and fits to the width of my screen, while when I'm signed out of c9 everything is centred and fixed width. I think this may be to do with custom CSS (reproduced below) in use on my profile, but I don't know enough about CSS to be sure, nor to know whether the CSS is at fault, or whether c9 is at fault. I'm using Opera 11.62 on Vista Home Premium SP2.

 When I'm logged in. Although it's clearly not designed to be viewed like this I kind of like it.

Custom CSS code:

body 
{ 
background-color: #FEFEFE; 
} 
.branding .toolbar 
{ 
background-image: url("http://images.callemin.be/c9/background.png"); 
background-position: center; 
border-color: #f08614; 
border-width: 4px; 
} 
.branding .navigation .logo a:hover{ 
background-image: url("http://images.callemin.be/c9/logo_hover.png"); 
  
} 
.mainHolder 
  
  
{ 
width: 90%; 
} 
.posts { 
float: none; 
} 
.posts > LI{ 
width: 90%; 
} 
.posts LI .post{ 
width: 85%; 
}
