I want to add a Comments section to a website page. This is for a publicly-accessible page, not a membership area page, not an eCommerce page.

Examples:

* obituaries

* real estate listings

* events

* photo galleries

* fan sites

* Q&A sites

Ideally, I could control the information required to be allowed to submit a comment (e.g. email address required) or use a social login (e.g. Facebook, Google, Apple, LinkedIn, etc.)
