Posting an action is super easy -- you can post an action by logging into your campaign. On the main campaign page, click Post An Action. You can then select from the group of actions to engage your community. Add videos or photos to your action to make it look great.
To edit your action once it's posted, go to the action page and click the top Edit link. To feature your action and pin it to the top of your campaign page, mouse over the action on the campaign page and click the link.
