Following the installation of a CAPTCHA block on the site I have changed the permissions for posting comments for non-members so that non-members can now comment on various pieces of content, subject to administrator approval. Administrator approval will be granted to any comment that is reasonable and not spam.

So if you are a non-member of my website community and want to add legitimate comments to the content on this site you can now do so without signing up as a member.

I have also changed the comment settings for Members so that a comment posted by a member doesn't require administrator approval before it displays on the website.
