Never gone near them, but I know someone who's fairly computer litterate (in the techie sense) and is trying to set one up currently. It just ain't going anywhere and because it's AOL you don't get all the manuals telling you how to get to the CLI and such.
It might be possible to do it yourself, but I'd guess you'll need all the AOL details and whether AOL support even know those is seriously debateable.
In essence - if you're not with AOL currently then avoid like the plauge, especially as cancelling it can be fun. And if you are, well, it should work but don't expect much help from them if it doesn't.
