This is an administrative update.
At the request of a few I have added a preview facility for the comments section. It is straightforward.
To submit the final comment you still have to be able to add up but you can preview the comment as long as their is text in the comment box via the preview option.
I have also been asked to install an E-mail alert for commentators so they can be aware of responses to their input. While I am sympathetic to the request the problem is that people do not give functional E-mail addresses in several cases. When I detect that, I delete the comment as per my comments policy but I cannot do that for all cases and so the alert system would end up sending me a host of bounced E-mails.
But at least the preview functionality will enhance you experience I think.
