I didn't get 100 association rep for Apple site http://apple.stackexchange.com/
The associations were already set, I cleared and reapplied from within the site and also cleared and reapplied from an account that already has more than 200 rep, but it hasn't applied.
I've also tried logging out and back in again as suggested in another post.
For every other site I've joined the bonus happens automatically when I join, not sure why it hasn't happened in this case.
