Grrr I wrote a long review on your spell and then my internet died.
So again in short ( if you have questions, feel free to ask )
1. Concept
Your concept is too simple for a spell submission nowadays.
2. Leaks
You have 6 locations leaks. ( Check out: Things that leak in may signature )
3. Indexing
Your spell does not have to be indexed, as there is no callback function ( periodic timer event ).
Also the way you index your spell is not good. ( Tutorial: Dynamic Indexing in my signature )
