 - **Maximum characters allowed?** -- You may set a maximum number of characters allowed in any comment. Setting this preference to 0 (zero) will not place a restriction on the number of characters allowed.
 - **Comment time limit** -- This is the optional number of seconds that must lapse after a comment is posted before that same user can post another comment. This setting can help reduce comment "spam". The preference can be left blank or set to 0 (zero) if you do not want to impose a limit.
 - **Comment expiration** -- The number of days after an entry is posted in which to allow comments. After that period has expired, the entry will be closed to commenting and the comment form will no longer appear. Existing comments will still be displayed. Enter 0 (zero) for no expiration. Note that this preference sets the _default_ setting for the channel. The setting can be overridden and changed on a per-entry basis. You may override this setting in the [Comment Module Control Panel](comment/control-panel.md) section of the Comment Module so that comments are set to be moderated rather than closed once the expiration period is passed. If you also select the checkbox accompanying this setting, then all existing entries in this channel will be updated to reflect the new setting when you submit.

+- **Text formatting** -- This setting determines how comments are formatted by the system. There are three possible choices: `Auto line break`, `None`, and `XHTML`
 - **HTML formatting** -- Like the channel setting, this preference determines how raw HTML code within comments is handled. There are three options:
 1. Convert to HTML entities -- This will convert any HTML tags to their encoded versions and output the HTML tag as text without rendering the HTML in the DOM. For example: `<h1>` would become `&lt;h1&gt;`.
 2. Allow only safe HTML -- This will remove any unsafe HTML tags as defined in the [Typography library](development/legacy/libraries/typography.md#html_format).

 - `"safe"` -- Allows the following HTML tags to be rendered in the DOM: `h2`, `h3`, `h4`, `h5`, `h6`, `abbr`, `b`, `blockquote`, `cite`, `code`, `del`, `em`, `i`, `ins`, `mark`, `pre`, `span`, `strong`, `sub`, `sup`. All other HTML tags are removed from the content.
 - `"all"` -- Allows all HTML tags to be rendered in the DOM. This is not recommended because it may allow users (who may not otherwise have access to edit templates) to inject HTML in unexpected places. For example, if the template is defined as `<p>{content}</p>`, but `{content}` itself is `<form><input></form>`, that will be rendered in the DOM as `<p><form><input></form></p>` which would essentially allow a user to add a form to a page via a `content` field that was probably not intended to be used in this way.
-- `"none"` -- Converts all HTML tags to their encoded values (e.g. `<h1>` becomes `&lt;h1&gt;`) and will output it as text. This is the safest option because it prevents any unexpected HTML to be rendered in the DOM.
