I thought AOL 6.0 uses Netscape 6.0 making the Marquee incompatible.
And scrolling long messages isn't the greatest idea. If a line gets too long they might use multiple lines.
They are three behaviors of marquee
* scroll
*slide
*alternate
Marquee were never meant to be long list of anything. Usually just a sentence @ most.
What is best though is JavaScript banner, where it displays one message after another automatically. A good example is
http://www.apple.com
But as lot of people say a signature is a signature. One or two quotes from maybe a famous scientist maybe all right. But not a bunch of crud that no one reads or do care about and just makes people mad because you have to scroll down to see the next reply.
