Settings that django_comments understands

COMMENTS_HIDE_REMOVED

If True (default), removed comments will be excluded from comment lists/counts (as taken from template tags). Otherwise, the template author is responsible for some sort of a “this comment has been removed by the site staff” message.

COMMENT_MAX_LENGTH

The maximum length of the comment field, in characters. Comments longer than this will be rejected. Defaults to 3000.

COMMENTS_APP

An app which provides customization of the comments framework. Use the same dotted-string notation as in INSTALLED_APPS. Your custom COMMENTS_APP must also be listed in INSTALLED_APPS.

COMMENT_TIMEOUT

The maximum comment form timeout in seconds. The default value is 2 * 60 * 60 (2 hours).
