I've released a new plugin for Nucleus CMS, NP_CommentPreview. A lot of Nucleus CMS users asked for this. CommentPreview is a replacement for comment form.

It features: * WYSIWYG comment preview. * it prevents same comment being posted twice for an item. * it features comment preview expiration after 10 minutes (users must authorize their comment again, if it is older than 10 minutes; you can set this interval in plugin options).

WYSIWYG preview features URLs conversion, line breaks conversion, bold, italics, caps, red, blue text, and also smilies
