Alright, I'm hooked: I've done everything so far with only occasional help from the official site, and am on Level 12 (thanks 420 for big help on level 10!). Level 8 is the absolute worst so far.
Remember to use their Google toolbar!
PS to Elessar: on level 11, you don't need to be vulgar to figure it out, but the answer itself is vulgar. You might need some freeware.
