Forum:The editor for wiki

Hi, there. I am a student in Taiwan and I've installed mediawiki (that's my homework). I found the create a new page link from the BIOSHOCK main page. (this link []) This editor can keep all the formats if I paste some content that I copy from another web page (including images and links). like this I think it's really a great editor and I want to install it for my wiki system. Can anyone tell me how to install this editor? You can just give me the website of this editor. Thanks a lot.
