Good points Jeff.
I think we could have slr groups and a mixed point and shoot group.
I still use my p&s, my 3 yr old loves camera tosses (seriously).
Most DSLRS can do the same thing, especially in our price ranges

, but the menu structures from manufacturer's are different. Not necessarily from model to model, but from Nikon to Canon, etc.
Groups for one meeting could be:
Canon DSLRs (understanding the menu's settings, etc,)
Nikon DSLRS (understanding the menu's settings, etc,)
Olympus DSLRS (understanding the menu's settings, etc, or just dunk my E-3 in a bucket of water

)
A chair for the pentax guy

All Point and Shoots (techniques)
Then another meeting the groups could be:
Lightroom/Aperture Users
Photoshop/ PS Elements/
ACDSee/ Picasa (freeware) / Gimp (freeware)
just a thought.
I think you can read manuals, books, etc. until you are blue in the face, but physical interaction with electronics makes me happy. Ok does that sound as bad as it reads?
