I did consider this, but I thought the email requirement would generally be enough to discourage spam, without adding too much of a hurdle to the commenting process.

I think if I get around to implementing anonymous commenting, I could certainly add an option for captcha. I’ll keep that in mind, thanks for the suggestion.

I will put that on my to-do list, thanks for the suggestion.

Admin(s) will be notified by email every time a new comment is posted, unless this feature is disabled.

As for an RSS feed, I’m not sure how this would work since Confab supports comments at multiple locations within a site… I don’t have much experience with RSS, but I’d be happy to look into it further if you would really like this feature.
