[Jprogramming] Feedback on beginner's code

[Adam Tornhill]

Hi all,
I finally decided to try to understand this fascinating language. So far I've spent some evenings reading and experimenting with the language. J is fun. Real fun. I also like how J forces me to re-consider how I view programming. Of course, that also means I'm still at a complete beginner's stage, so I'd like to ask for some feedback and suggestions on my first J code. I'm sure there's a lot I can simplify in my code.
Here's the code I put together by digging around in the J Dictionary:
isAnagramOf=:(0:`((*/)@(=&((/:~@tolower)@(' ' & i.#])))))@.(=&(#@:(' ' & i.#])))

Some examples: 
  'Nag a Ram ' isAnagramOf 'Anagram'1
   'ab' isAnagramOf 'aa'0
All tips and hints on both the code and learning J in general would be much welcome.
