Description: Adds a customizable poll to your sidebar. You can have any number of options, and the poll is randomly selected from a list of enabled polls. <b>Important:</b> When first loaded, this plugin creates the following tables in your Enano database: enano_polls, enano_poll_options, enano_poll_results

Author: Dan Fuhry

Version: 0.3

Author URI: http://enanocms.org/

Changelog:

  9/27/06:
