Well I have the following diclaimer on the main page:

This site is informational in nature. Current NOTAMs are available from
Flight Service Stations at 1-800-WX-BRIEF (1-800-992-7433). Notices,
restrictions, and advisories may change at any time and without notice.
Do not attempt any operation in the National Airspace System without
first obtaining and understanding a thorough pre-flight briefing.

Which is the same disclaimer the FAA uses on the PilotWeb site.
