Portal free on steam until the 24th.

Hum, well when I said, "I don't think its free," I was referring to Portal.

Yes, Portal is free.

So your telling me that by downloading it on Steam, I now have it forever?

Yes.

EDIT: Forgot to mention, only reason I'm downloading it for my PC is that I want to play Portal Prelude.

Should not be a problem... The mods directory is within the Steam / SteamApps folder structure.

EDIT2: Steam says: "a source engine game is required to run mods" . WTF is that all about? I have Portal installed for crying out loud.

I would think Portal qualifies for having a Source engine game. ( The others being CS: Source, TF: Source, HL2: Source, etc...) Make sure you have the mod installed in the correct folder.
