Quoter allows site users to quote one or more comments, in a similar way to forums. The quoted comment is pasted inside the comment form textarea, wrapped in [quote] tags that, once submitted, are replaced by <blockquote> preceded by quoted comment information (author, date...).
It’s also possible to quote any part of a page’s text, not only a comment, by selecting it and clicking the “Quote selected text� link. This feature only works if Javascript is enabled.
This plugin is totally configurable via Admin Panel.
