CNET News.com is reporting that Yahoo on Tuesday will begin offering 100MB of extra storage for users of its free e-mail service. “Along with the 100MB boost, Yahoo will upgrade Mail Plus paid users to 2GB of storage and lower its yearly subscription from US$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. The storage boost comes as no surprise. Yahoo arch-rival Google in April announced plans to launch a free e-mail service called Gmail with 1GB of storage.”
