SCANALYZER is moving. After 2021-10-31 (Hallowe'en!), SCANALYZER is moving to the new SCANALYST site, a Discourse-based discussion forum which will publish all of the current content from SCANALYZER and allow members to comment, discuss, and write their own posts on any topic that interests them.

All content posted at SCANALYZER since 2021-10-04 has been mirrored at SCANALYST, so if you follow this site, just change your bookmark to read all of the same content and more there. If you like what you see, sign up to comment and share your own posts with a like-minded community. SCANALYST has no subscription fees, no advertising, and requires no personal information other than a valid E-mail address to confirm your sign-up. We will never knowingly disclose any personal information about users. Almost all posts at SCANALYST, and every one in the SCANALYZER categories, are readable regardless of whether you sign up or not. If you sign up, you can comment and write your own posts.

SCANALYST is a forum for civilised conversation. Other than momentary lapses of reason, disruptive or abusive behaviour will result in immediate exclusion from commenting or posting at the site without possibility of appeal. There's already too much coarseness in today's world: we don't need any more.

If this sounds like something in which you'd like to participate, just visit the site, click “Sign Up” at the top right, and jump in.

I hope to welcome many readers of this site to SCANALYST.
