Terms of Service

Use of this site is on the terms below. They exist to be clear about what published guidance is and what it is not.

Revisions to These Terms

Amendments to these terms take effect when they are published on this page. No separate notice is given, so the page itself is the reference.

Limitation of Liability

Decisions taken on the basis of anything read here are the reader's own. To the extent permitted by law, no liability arises from its use.

Not Advice for Your Job

These guides address the typical case, never a particular property. Where what is written here conflicts with what a qualified professional says about the actual job, the professional is right.

Third Party Sites

Other sites are linked on merit and nothing more. Their inclusion is not an endorsement, and those sites are outside this one's control.

Intellectual Property

The writing on this site is not free for reuse. A brief quotation with attribution and a link is fine, wholesale reproduction is not permitted.

No Warranty of Accuracy

The material is prepared carefully and still cannot be warranted as complete or up to date. No guarantee is offered that every statement is correct or current: codes are amended, products are discontinued, and prices move.
