A couple of my colleagues have taken it upon themselves to share their knowledge and experience using Forefront Identity Manager (FIM) in the real world. I've had the privilege of working with them wherever I could and being able to contribute to a small part of the knowledge on the site. Their new site is appropriately called “the Connector Space” and can be found here: http://blogs.msdn.com/b/connector_space/
In it, you can find tips & tricks, documentation, scripts and more. Check it out. I know you’ll find it very helpful if you have anything to do with FIM.
