Groups provides a way for two or more people to work collaboratively online. In a group you can share documents, conduct topic-based discussions in a forum, create and manage group-specific events, and send private messages to group members. Groups can be Public (any registered site user can join), Private (users must request membership), and Unlisted (private group that does not show up in the group list). You must be a registered DME site user, and logged in to create or join a group. To register for the site, please contact email@example.com.
