TerminalFour has a few handy options for content types that you may wish to keep in mind.
Each content item has the option to have a Publish Date, Expiry Date or Review Date set for it.
To access these options first you have to select and edit the piece of content you wish to set a publish, expiry or review date for. Once you've entered the edit mode for the piece of content you will see a tab at the top of the screen that is called "Options". Select the Options tab. Under this tab you will see Publish Date, Expiry Date or Review Date options.
