The FENS forum can be viewed by all, but only members may add new posts, and membership is limited to the MIT community. It requires an @mit.edu email address.
For your username, you need to use your Kerberos name (whatever precedes the @mit.edu in your email address). But, you should choose a unique password.
All membership applications are reviewed by an administrator before acceptance. Submitting this form does not guarantee access to the forum.
