Scope of what is published

What is written here is general information. Nothing here is advice, and none of it was written with a particular reader's situation in mind.

How current this is

Subjects change. Something accurate at the time of writing may be stale when it is read; no undertaking is given either way.

Sites linked from here

No link here should be read as approval. It notes where else the subject appears, and that is all it means.

Amendments

Should any of it change, the updated version supersedes the previous one once it is on this page.

If something here is wrong
