Offroadcode Social meda datatype.
This package will create a content type which will show the profile image and profile name for the entered alias as they are typed by using ajax. Resulting in feedback to the user so they know they have entered the correct alias.
The default social media providers are for Facebook and twitter, You can create your own profile provider simply by implementing the ORC.SocialMediaEditors.ISocialMediaProvider interface. Youre implementation will automatically be picked up by umbraco and become available in the pre-value editor.
You can watch a demonstration of facebook and twitter examples here
I have added a link to the users profile from the datatype.
