Tomorrow AOL will introduce a beta version of AOL Instant Messenger Mail. The new webmail service from AOL will be fully integrated into the second beta of AIM 5.9 and will offer its users 2GB of storage capacity.
The AIM Mail service is tightly integrated with AIM and uses Screen Names as the prefix for members' e-mail addresses. Moreover, Screen Names are used as a single sign-on for both services. Users can access AIM Mail by invoking it trough their AIM Buddy List or through the Mail panel located within the AIM Today welcome screen.
