How do I copy my wiki?

Can I duplicate a wiki? I want to give a colleague a copy of my wiki so that she can use it with her class. She'd like to customize it for her own use, add her own notes etc. Is there a way to copy the wiki (and all of the files I've uploaded) to another account for her? I don't want lose my stuff, and I would rather not have her teaching notes interspersed with my own...
