A series of puzzles, very hard puzzles, and I can't get past level 5. Can't explain. Won't. Can't. Mustn't. What you do is change the end of the url to what you think the answer is. So if your answer was 5, you would change the url from /~clabulis/levelone to ~clabulis/5

Hot damn, this is an interesting puzzle...

This is pretty fun.

Edit: Also now stuck at level five. But I feel horribly close.

Edit2: Are there any words for !, #, %, and & other than exclamation mark(/"point" eugh), hash, percentage, and ampersand?

Edit3: Ffs. American keyboards have the # on the 3 key.
