An organization that collects money using the fundraising module may have some legal obligations where they must refer to the fundraising money collected with specific wording, like contributions or donations instead of gifts. You can choose the word that you wish to use by indicating the desired term under Setup>System Terminology>Donation/Contribution. See Setup Your Terminology for further instructions.
NOTE: This setting will only update the public donation page. The system term is used in the back office.
