Thanks, Kaptitsky, for the links. But, reading the FAQ (
http://beta.aol.com/projects/aimmail/index.html?loc=3), I am not sure if this is the new mail system announced today. Firstly, they state that the storage quota is 250 MB and not 2 GB. About accessing your email, when asked if the mail is accessible using an email client, they say "AIM Mail is a web-based email service and is not accessible using email readers."
Anyway, the system seems good and fast using Internet Explorer. And messages goes out and in very fast too.
But I can't access it using Firefox (1.0.4, just released). After loging, when ending the load of the webmail, my Firefox is resetted, dissapearing from the screen (some cookie must be available, because, when accessing again, it remembers my username).
