FYI there is a chance that you can all enter the chat.
AOL have told me that you needn't be on aol to join their chats.
You simply need to download AIM (aol instant messenger), sign up for a screen name and on the appropriate day visit
http://www.aol.co.uk/communities/chat.html
and join the chat. AIM will launch automatically if you have signed up, and you will be able to enter the chat.
If you look at the chat page now and can't see the 'live chat' option then there isnt one on at the moment. Don't be disheartened though as in the past they put up the link about 5 minutes before the live chat.
If you want to download AIM you can do so here:
http://www.aol.co.uk/aim/aim47.html
It's free.
To sign up for your screen name you need to visit here:
http://www.aol.co.uk/aim/register/register.adp
I have no idea if this method will work - AOL have told me it shoud (about 85% confident) but if you're a real fan, be sure to give it a go. Good luck.
