This Tuesday Yahoo will begin to offer 100MB of additional storage for users for its free mail, as part of a strategy to redesign the service.
"Along with the 100MB boost, Yahoo will upgrade Mail Plus paid users to 2GB of storage and lower its yearly subscription from $29.99 a year to $19.99. Other a la carte services, such as POP e-mail forwarding, will consolidate under this plan and no longer be sold on a standalone basis."
Aside from this additional space, there are also plans to make the e-mail service a lot sleeker, faster and cleaner.
