How to edit
First, you must register for a user name and log in; anonymous edits are not permitted on this Wiki. (Note: account creation has been disabled for the time being due to spam; contact Steven G. Johnson to get an account.)
Then, click on the edit button at the top of the page. We use the MediaWiki software, which is the same as the Wiki software that runs Wikipedia — detailed instructions on how to edit and format pages can be found at:
To practice, try editing in the Sandbox.
You can link to a Wikipedia article by prefixing "w:" to a link, as in w:Photonic crystal. Users looking to write general articles not specific to the MIT software should go e.g. to Wikipedia instead of here.
MIT users should contact Steven G. Johnson to obtain administrative privileges, so that you can protect pages on your personal work from editing by the general public.
