Why it's closed

This used to be open. Here's why it isn't anymore.

This started as an open, edit-it-yourself archive. On a serious note, that did not work the way it was meant to — a few people did the work, and material that should have been gated was sitting out in the open.

So it is a closed room now. No pull requests, no public edits. If you spot a genuine error, sign in and flag it in that session’s discussion — that is enough.

Everything else — why the login, why one session a week — is on the About page.
