Brilliant Web-to-Lead for Salesforce
Formerly known as WordPress-to-lead for Salesforce CRM
Description
Brilliant Web-to-Lead for Salesforce creates a solid integration between your WordPress install(s) and your Salesforce CRM account! People can enter a contact form on your site, and the lead goes straight into Salesforce: no more copy pasting lead info, no more missing leads: each and every one of them is in Salesforce.com for you to follow up.
Check out the (slightly out of date) screencast

You can fully configure all the different settings for the form, and then use a shortcode to insert the form into your posts or pages, or you can use the widget that comes with the plugin and insert the form into your sidebar!
