You can see a list of all the actions your group has published clicking the "Actions" tab below the main section on your group's participate page.
There you will see a list of all the actions sponsored by the group, both published and in draft, as well as who created the action, how many actions/letters it has, any tags it has, whether the action is in test mode or not if the action is a letter campaign, and the action's public title and administrative title and the date it was last modified, and any notes you've added.. Click on the action's title if it's published to see the live page. If the action was created by you, you'll see an editing button you can click to edit that action.
