As interpretation of the MLA categories varies (especially when dealing with something such as Everything2 which has no set entry style), here is the default "internet source" style with E2 values:
Username. [user e-mail address if you can find it]. "Node title." In Everything2. [http://www.everything2.com/index.pl?node_id=<insert node_id here>]. timestamp.
Be sure to include all punctuation that I have shown! It is very necessary when you wish to follow the MLA style!
For a full example, here is the one I just made for my paper (it'll be noded once I finish):
Muke. "Dvorak." In Everything2.

UPDATE - I was incorrect. I should not have included the line breaks.
