Things you can put
on your website.
Free reference pages your donors, your board and your colleagues can use, as links you can paste in. Every rule on them carries the official source it came from and the date it was last checked.

THE BUILDER
Pick one, and take the code.
The preview is what visitors to your site will see. The HTML below it is what you paste. It carries its own styling and no class names, so it looks the same on your site as it does here and cannot collide with your stylesheet.
THE CATALOGUE
What there is,
and where it goes.
Each of these answers a question your visitors already ask. The third column is how much of the country it covers.

THE TERMS, SUCH AS THEY ARE
Free, and not a trade.
Use any of this without asking and without an account. No attribution is required, nothing is tracked, and there is no script to install. We do not ask for a link in return for anything, and nothing we sell depends on your linking to us.
If a page you have linked to stops existing, write to [email protected] and we will tell you what replaced it. Addresses in this section are meant to stay where they are.
What a link here is not
It is not compliance. Your own required notices, your policies, and the written acknowledgment for a gift of $250 or more still need their own placement and their own wording.
It does not speak for your organization. These pages explain the rules a donor or a nonprofit lives under. Your gift terms, your restrictions and your refunds are yours to state.
And it is not our endorsement of you. Please do not present it as one.
