|Connections - http://wordpress.org/extend/plugins/connections/|
directory plugin available for WordPress. There are fields for addresses, phone numbers, email addresses, IM, social networks, an image, a logo, bio, notes and more. Want more? Many fields, such as addresses and phone numbers, you can assign as many as you need. Wait, I'm not done yet... want to be able to list the business phone but keep that cell phone number private? You can do that, too. Most of the fields have selectable visibility. What this means is you can have an entry set as public but keep personal details private or even unlisted so only them admin can view it.
