Since everything is in the body content, between <body></body> tags, you can't really change the overall background. But, you can just create a huge table, or frame, and change the background color within that. So it's basically close enough.
Changing text color is fairly simple..use the <font color=""> ?
Since there is no head include, you can't really add custom css stylesheet code, to change link color.
Maybe there is a way to do it using
Code:
<a href="http://www.mysite.com" style="">
?
I'm not sure, never tried.
