The intent of this list is to help you help yourself. If you spend the time to
take Arun's ideas and run with therm, then you will do us and yourself a favor.
We will benefit because you can then help others with similar problems, and you
will benefit because you don't need to worry about failure to communicate out
delays from us. Even if you cannot completely figure it out on your own yet,
giving us your attempt every tone you post can demonstrate your participation
and help clarify what your intent is. But asking us to just "do it" for you is
not in the spirit of this list.
