This may not be super geeky, but it’s a super great deal.  You can pick up Youth Leader Training on the Go for only $7.99 (Retail $29.99).  It’s a great resource from Doug Fields for keeping your volunteers trained and encouraged.  It contains 52 training sessions that work great in your team meetings.  Plus an audio CD with 12 short audio trainings, and a CD with all the handouts.  It’s worth checking out.
