December 17, 2018: The Wikispaces platform has closed. Wiki organizers who need an HTML export should contact the CTL as soon as possible (ColumbiaCTL@columbia.edu) before they are no longer available. Please provide the name of wikispace needed.
Tangient, the company that hosts the Columbia Wikispaces, has informed us of their intent to close down the platform by the end of this calendar year. Please learn more here. Accordingly, Columbia will stop hosting class wikis at the end of the Spring 2018 semester. We are also generating documentation to help our faculty export their content from Wikispaces and compiling a set of of alternate platforms.
