WP petition plugins can offer such functions as add petitions to your Plugins for WP and create forms for such petitions so that visitors may fill them up and they be copied automatically with the copy being sent to the email of the person or organization to whom the petition is addressed.
Organize petitions easily and efficiently
Modules allow the signatures of visitors who show their support of the petitions to have their signature contained within a database that is capable of being exported completely to be analyzed more. Addons also allow goals to be set up as to how many signatures you require, using such objects as bars to demarcate how much progress has been made. Several governments also provide addons that allow petitions to reach them directly, which may be integrated to your WP site. Then there are the extensions that also allow you to create polls for voting on an issue out of which a petition may be made, to gauge the general opinion with regard to the people who visit the website.
Customize petitions fully to your liking
Modules enable you to fully edit the petitions that you create and also add their WordPress Form Plugins as well as signatories, to the pages of your WP site or the posts you make. More of such inspirational petition addons are available for use at BestPlugins, a module library you should certainly check out.
