Will they learn what I need them to learn

Yes, but a lot more.  ICCM is not simply geared towards teaching someone how to fish.  It is all about also introducing them to all the other fishermen in their waters.  It is all good to learn how to fish, but when you are a part of the fisherman’s guild, you have a bunch of people to discuss the weather, where to get new nets, etc.  ICCM brings techies into a techie family; not only for learning one topic, but for giving you friends with which to discuss ongoing topics.  Even if it looks like there are no topics that meet your current techie’s needs, you will find that they will get a LOT out of ICCM.
