For those who are trying to master WILD'ing, this seems like a decent resource:

It's long-winded, a little strange, and the writing style is sloppy, but it still looks like there's plenty of good exercises for beginners.

Personally, I'm busy trying to have DILD's, so I can't really say if any of it works. Just thought I'd pass it along.

Enjoy!
