Extract it into the portal folder and everything should go into its proper sub directory.
I need feedback on two things, specifically, as well as any errors you encounter:
Whether Shmitz's map has the proper voice-overs (from GLaDOS). It was only working erratically on my computer, but I think that may be a local problem.
Whether you get "Node graph out of date ... Rebuilding" messages when you load any of the maps. I tried to include those in the zip, but I'm not sure if Portal will treat them as legit for some bizzare reason.Thanks.
