RandomText is a handy WordPress plugin that allows you to save, edit and delete categorized text, and inject random/rotated text by category into the sidebar (via widget) or page body (via template tags). The sidebar widget allows you to set an optional Title, and text header and footer. You could say RandomText picks up where the Text widget left off. Whether you want to display random/rotated trivia, quotes, helpful hints, featured articles, or snippets of html, you can do it all easily with RandomText.

This plugin provides the ability to have randomly selected quotes displayed on the admin page, by using a 
shortcode or by using a sidebar widget. The quotes include user-entered quotes, and can optionally include 
excerpts from a user-chosen category and can also optionally include links from a user-chosen links category 
There also is an option for including the lyrics from “Hello Dolly”. The plugin can be used for random
