If you're catering almost exclusively to Windows IE users, it's easy.
Code:
<marquee behavior=scroll direction=up scrollamount=1 height=60>
<p><center><br><b> This Text Goes Up From Down <br>
</marquee>
We have that set up as a custom BB code...
It works in IE for Mac, but looks bad.
It ONLY works in IE though... it's a proprietary tag.
If someone can find a good DHTML/JS scroller that works sideways and in Nutscrape, I'd love to have it.
