Got a note yesterday that the folks from MSDynamicsWorld.com and the folks from Dynamics Communities (the GPUG people) are working together to leverage their various strengths. I think that this will be good for the community and helpful at getting news and issues out to users. More info here.
MSDynamicsWorld and Dynamics Communities Collaborating.
Archived post from 2008. Dynamics GP and the links it points to have changed since; check current documentation before relying on version-specific steps.
