Warning regarding edit time before user submits a topic

[Morgin]

My mods have asked if it is possible to have a line of text added above or below the submit post / submit topic button to remind users of the amount of time they have to edit a post before it is no longer editable or removable and a general warning about posting personally identifiable information. We are getting a lot of new users who expect us to operate like Reddit with an ability to delete content at any time. Without getting into the rationale, our community doesn’t operate that way (and we’re not bound by any of the regulations that would require us to make that an option).

Is this something I could do with the stock software editing a language string, or would I need a plugin to achieve this?
