## What the statuses mean

- **confirmed** (ACK): a person from OpenACK signed in with a test account and saw it work.
- **not confirmed** (NAK or ?): it was tried and didn't work, or we couldn't reach or check it. Not proof it's missing, but not verified.
- **not evaluated** (—): nobody has checked it. It's the founder's word only.

Treat only "confirmed" as verified. A result is a record of one evaluation on the date shown, not a guarantee.
