Revising Java Boot Camp Presentations

I've just finished writing my two presentations on Object-Oriented Programming and Object-Oriented Design, and now I've been spending two days writing my grand opus on "Working with Objects". These will change the world! Haha, I'm having delusions. ;-) Anyways, I'll post these presentations for free download once we get to overhaul the O&B site.

Speaking of overhauling our website, has anybody here tried Apache Lenya? Would you recommend it as our CMS? How about the XWiki for our external wiki?
