Google has a "Help" page for members to help them figure out the particular solution to their particular issue. For the quickest solution to your GoogleGroups problem, check "Help" before posting questions to the list or moderator -- if you can't find the answer under "Help" (the link to "Help" is at the upper right corner of the GoogleGroups screen after you log on), then ask for help.
