Collaborative Documents Online

Think Free is a collaborative documents site, that allows you create, view, and edit Microsoft Office compatible files over the web. You and your friends can collaborate using group editing and file sharing, edit, read and post your documents online. Free users have 1GB space.


Another similar site is Approver, it is also free register but I am not sure what size of space for free users.


Think Free是一個合作性文檔共享網站，它讓你在線建立、浏覽文檔和使用Microsoft Office的功能。你和你的朋友可以共同使用小組功能來編輯和分享文檔，在線編輯、浏覽和發布你們的文檔。免費用戶可得到1GB空間。
另一個類似的網站是Approver，它也是免費注冊，但我不知道它的空間多少。
