A great way to promote a MoveOn petition campaign is to feature it on your blog or site. This plugin embeds petitions into your content and theme. Your readers will be able to view and sign these petitions in place. For more on MoveOn’s campaign tools and petitions, please visit http://moveon.org.
This plugin provides three ways to integrate a campaign into your site:
<ul>
<li>A sidebar widget: a new MoveOn Campaign widget type will appear, and be eligible for placement in your widget areas.</li>
<li>A shortcode: use the <code>[moveon-campaigns-petition]</code> shortcode in your content to embed a petition directly in a post.</li>
<li>A template function: you can call the function <code>moveon_campaigns_petition</code> from anywhere in your theme.</li>
</ul>

MoveOn Campaigns

Display and sign MoveOn.org campaign petitions on your site.  Integrate directly into you theme or content, or use as a sidebar widget.

The Louder Campaignlist plugin will display a set limit of campaigns (including optional campaign logo) with links to the relevant Louder campaign page, drawn from the selected Louder directory category. So you can display links to campaigns of specific interest to you and your readers in, for example, a column in the sidebar of your blog.
Louder is the new home for e-campaigning. The site draws together a range of online activist tools enabling activists to create and run their own campaigns and connect with others with similar interests.
