So basically, you want the page to load, but load so that the scroll bar is far enough down as to ignore the myspace ads? let me know if this isn't correct.
You have a couple options: you can access the scroll bar directly through javascript/DHTML, or you can set an anchor a few lines down, and then onLoad, call a javascript function which jumps to that anchor. I don't remember the code on how to do this at the moment, but it should at least give you an idea of what you will have to do. If you are new to HTML, this can be a bit daunting...I would recommend the ANCHOR method and see what you can do.
Depending on how this banner is implemented, this may or may not work.
"You can position any output to the screen using CSS. Easiest is to use <DIV>s for that."
- True, but I don't think this is what the Original Poster was goin for.
IMPORTANT: You may want to look into the rules and regulations for your web hosting service...the ads are there because, well, ...like you said, its FREE. Free is good. Free is free. By bypassing the ads, you may be breaking rules of conduct , and could have your site removed, and/or you could be banned.
