I have a quick question though. Your submit comment script says that the emails submitted won't be seen by anyone, but I can see the email address of folks that have left comments in the link with their name as "mailto:email@example.com".
So these email addresses are visible to the world at large, as such, isn't it?
Another point - Maybe you could have a question
"would you like to receive emails when replies are posted?" Yes/No
so people can submit their email as always and then choose not to get an automated email when a comment is posted.
And - would emails be sent to only when replies to the same comment are posted, or also when someone leaves a reply to a comment posted in response to the comment. (quite involved, but I hope you see what I mean.)
:) I was just thinking about the lack of this email notify feature in threaded comments yesterday.
Thanks, I will probably get it working soon.
