Changes to Terms — now high risk. The Wikimedia Foundation can change these terms at any time, and if you don't agree, you can stop using their services.

No Warranty. If their outage costs you money, the most you can get back is what you paid them last month. Since the service is free, you won't get anything.
Report Problems. If you find a problem, you should report it to the Wikimedia Foundation. They may be able to help resolve the issue.
License Requirements. When you contribute to the Projects, you must license your work under a free and open license, such as CC BY-SA 4.0.
Account Blocking. The Wikimedia Foundation can block your account if you violate their terms. If that happens, you won't be able to use their services.
Data Collection. The Wikimedia Foundation collects and uses your information according to their Privacy Policy.
Trademark Protection. You should respect the Wikimedia Foundation's trademarks and not use them in a way that could be confusing or misleading.
