I want to make a starter for my next brew. Do I add the yeast nutrient before or after the boil? Does it ever matter?

Recipes 

I would go with after the boil while the liquid is still warm, if all else fails read the instructions
I have used it in the past with weaker dry yeasts (muntons, coopers) but most of the time I just go with out

Follow the instructions. Usually added at the end of the boil.
Yeast nutrient is not usually need for brewing beer. It is however an important step in making mead and many wines.

Sounds like DAP... You can use that either boiled, or post boil. Most beer nutrients include instructions to add in either the last 10 or 15 minutes of the boil.

I typically use [Wyeast] beer nutrient in my beer, and DAP in my mead/other fermentations.
