@ Knightmare : Just go to the admin CP and in the shoutbox
section choose
configuration. There you have all you need
to change the background color, and some other colors too


.
[edit]errr. for the background of the reduced shoutbox... the
colors are those from your styles.... so maybe you can change
the font colors of the shoutbox for it to be more 'readable' (argh
frenchie cant write

).[/edit]
@zootsuit : I'll have a look on the changes you have to make
for the shoutbox to be in a popup

.
[edit]here we are

...
i think that, for the shoutbox to be in a popup, you just have
to add, on the footer, for example, something like :
Code:
<center><a href="javascript:window.open('shoutbox.php','left=100,top=100,height=130,width=150,scrollbars=0,status=0, location=0,resizable=0,menubar=0');">Shoutbox popup</a></center>
Don't forget to get rid of the space between java and script

.
I cant remember if the top bar is included in the size of a popup
or if the size is the internal size so you will maybe have to change
the height parameter

...
Tell me if it fits
