Program statuses are the checkpoints through a programs path (channel). If you make a status by mistake or no longer need it, feel free to delete it.
Go to the Admin section.
Select the channel you want to remove a status from, then under Tag Actions, click Edit.
Click to remove the status, then click Save.
If any person is currently assigned to the status in question, you cannot delete it, you can however hide it.
Nicely done! You can also delete an entire channel if you need to.
