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.
Third Party Sites
Other sites are linked on merit and nothing more. A link is a pointer, not a recommendation of whoever is at the other end of it.
Use at Your Own Risk
Decisions taken on the basis of anything read here are the reader's own. Nothing published here carries a guarantee of outcome, and no claim arising from one will be entertained beyond what the law requires.
Reuse of Content
Copyright in the material here is retained. Attribution with a link earns a quotation; scraping the page does not.
Revisions to These Terms
What appears on this page is the current agreement. Earlier versions are superseded rather than archived.
General Information Only
No article here constitutes advice for a specific project. Where what is written here conflicts with what a qualified professional says about the actual job, the professional is right.
Accuracy
Every effort is made to keep this material correct, without any guarantee that it is. Anything load bearing on a decision should be verified against a current source before it is acted on.
