Hello CJ

I too am troubled with the use of "for" and "to". My problem is which preposition to choose for which adjective.

1. 
   
   English proficiency is necessary for/to your business success.
   


2. 
   
   Energy saving is important for/to the control of CO2 emission.
   


3. 
   
   Let's meet at two tomorrow afternoon if it's convenient for/

This may be an American/British distinction. Here are my preferences.

1. necessary for
2. important for (but "important to (person)")
3. convenient for
4. useful to (person)
5. useful for (thing, activity)
6. easy for

Thank you, CJ. So I'll take it as the rule of thumb to choose "to" for persons and "for" for things with the exception of "easy for persons".
