Just as the title says, there is a website that is an official anime streaming site where you can watch anime for free. I checked the site and it is legitimate as they have recognized by ANN alongside Neon Alley and Crunchyroll. Surprisingly, they have a variety of series on there from Lupin the 3rd to Zeta Gundam to Dragonball Z. Here is a link to their site and you can check the legitimacy for yourself.
Edit: I understand that as a general rule, we do not post links to online streaming sites (as most are questionable at best), but keep in mind that they have shareholders much like Hulu.com
Update: It was announced at AX right here in LA that Daisuki has acquired a license for get this… Gundam ZZ! The article can be found here at ANN.
