Anyway, what happens when you upgrade? Does anything get messed up or do you lose anything?
I'm afraid to do it, but I think I'd get more webspace 'cause you're allowed more screen names.
When I still had my web pages on AOL spread across multiple screen names, I switched to a newer version that allowed more screen names thinking it would get me more web space. Turns out AOL just redistributed the existing web space across a larger number of screen names, meaning less web space per screen name. Several pages and images were lost in the process. If you upgrade but don't create new screen names, this shouldn't be a problem.
Of course, another option in order to avoid being wrapped up in all of the AOL upgrades is to track down a free web space provider.
You probably already know about this.
www.esmartstart.com has multiple domain names to choose from and offers up to 20 MB of free web space. Their Terms of Service are fairly standard.
