MoD reader jetslandingboard writes in that the RAHAGA combiner instructions are online, not at BIONICLE.com , but at http://www.lego.com/eng/buildinginstructions/ . Select “Bionicle” (gasp!) from the Categories drop-down list.

Update: RAHAGA combiner instructions are now available from BIONICLE.com’s Products/Building page for those who don’t like .PDF files.
