Ah. You'd think those would be in the instructions... hrm. Well, it's now enabled... let me go edit the file to remove the pipe (I knew something but not enough...), and see if it works.
If I may make a small tweak to the mod instructions (I know they're getting tweaked...), you might want to put something in under 2 Mod Mechanics that explicitly states how to enable a Mod (through the Mod Preferences). It tells you what happens if a mod is active, but not really how to activate/enable it.
Thanks for all the help, though.
