This is an official ODERSA website. Here’s how you know

The official domain

The address of this site ends in odersa.org. Every service the association runs sits on a subdomain of odersa.org and nowhere else. If the address in your browser’s address bar does not end in odersa.org, this site is not ours.

Free, and no account

Everything is open straight away. No sign-up, no account, no password, no subscription, no advertising. Nothing is held back for those who pay, because there is nothing to pay for.

No data collected

This site does not follow you: no tracker, no tracking cookie, no measurement tool built into these pages, and nothing measured on your device. Our host counts requests in aggregate, as any server that answers does: a total, never a profile. You do not have to take our word for it: open your browser’s developer tools, go to the Network tab, and reload the page. You will see the full list of what the site asks for. Everything comes from odersa.org, nothing goes anywhere else.

Free to reuse

The content is published under the CC BY 4.0 licence. You may copy it, translate it, print it and pass it on, for your classes as much as for the people around you, on one condition only: credit ODERSA.

Report an error

A site that teaches people to check things must be open to being checked itself. That is the point of this page, not a courtesy.

The message goes out through your email software, to the address literacy@odersa.org. It asks for three things: the page concerned, what it says, and what would be right.

If your browser opens no email software, write straight to literacy@odersa.org, giving the address of the page.

What counts as an error

An error, in the sense of this page, is one of these things.

What is not one

Two things are not errors, and are not reported here.

One case stands apart. This site teaches artificial intelligence, a field where the state of knowledge shifts and where some points remain debated. A statement presented as certain, when its source gives it as debated, is an error in the sense of this page. The association wants to know.

What happens next

The report is read. The source is opened again. The page is corrected, then republished. Nobody needs to give their name: no data is kept beyond the correction.
