I just fininshed watching a webinar produced last July on three important learning activities offered by FamilySearch. They are online classes, the Wiki, and Forums.
The show lasts about 30 minutes and gives a great overview of what each of the three areas has to offer and how to use them.
I found the Wiki especially helpful, since I personally have been having trouble finding some things on the FamilySearch website since it's make-over last year.
