Check out http://www.arrl.org/field-day.

The rules are in a PDF.  Here's what it says about class D:
(Class D) Home stations: Stations operating from permanent or licensed 
station locations using commercial power. Class D stations may only count 
contacts made with Class A, B, C, E and F Field Day stations.

Also:
Phone, CW and Digital (non-CW) modes on a band are considered as separate 
bands. A station may be worked only once per band under this rule.

So you can work a station once per band per mode, (i.e.) you can work a 
station on 20 meter SSB and CW, but not twice on 20 CW, for example.
