Group Managers are able to remove members from the group. Additionally, a member can remove themselves from any group they are in. Here are the steps for each - note that for either option, you must be logged into the GroupValet website at www.groupvalet.com. This cannot be done in the app.
Group Managers Removing a Member
Once logged into the website, click the My Groups tab. Find your group and click the "Go to Group Homepage" button. Next, on the left side, click the "Manage" tab and then click "Remove Member".
Check the members you'd like to remove. Note that if the person's name is not in GroupValet, and only their email is, they will be at the bottom of the list.
Click "Next" and confirm the removal. The members will NOT receive a notification that they have been removed.
Member Quitting a Group
Members are able to leave any group at any time. Simply follow the instructions in this article.
If you want to disable the notices for a period of time rather than leaving the group, see this article.
