It takes time and care to create a great action on Causes. You can save drafts of your actions before posting them and see what the actions will look like when people visit your campaign. To save a draft of an action, click the Post an Action button at the top of your campaign, start drafting, and select the Save & Preiew option.
Once your action draft has been created, you can go back to edit your action at anytime by going to Actions tab of Manage Campaign. You can also collaborate with your other campaign organizers and have them make edits by going to Manage Campaign.
