*Wikispaces is free to use; if you sign up for an educator account you get lots of customizable allowances, and the teacher can set up usernames/passwords so the students don't need email addresses.

PB Works (also called PB Wiki)
***Frisco ISD also has a wiki. If you would like a wiki through the Frisco ISD Apple Server, email your class rosters and the name you'd like to call your wiki to your technology facilitator.
