Can I email my members?
Yes - keep in mind that each time we create a card, this is by default emailed out to members with an email address. Cards are a great way to communicate with your group as the conversation lives on the group board and can be commented on by the group publicly.
However, you can also choose to send a more traditional email to group members by visiting the Members pane. From the list of group members, in the upper right of the list click on the mail icon to open an email window to group members. Keep in mind this email will not be recorded on the group board and replies from members will be received only by you, the group organizer.
