all you need to do is make a note of all your Emails or mail to your contacts after the change with new email address.
Easier as even though when you have left aol for around 3 months after u will be able to log into your aol and get mails, but any saved emails will be lost when you uninstall the AOL software.
The pub quiz will work fine with any other isp.
Recomend for price if you got Sky their broadband would cost £10 month !
Personally, go and ask AOL for your MAC Code to pass on to your choosen new ISP
