The National Resource Defense Council has updated six-month-old social site ItsYourNature.org with the inclusion of a widget that tracks user activity.

Geared toward “cultural creatives,” the widget features a calendar of concerts with options to order tickets, send messages to friends via mobile and email, and save events to a personal calendar. There is also a news section, reports DM News (via MarketingVOX).

Created by Gydget, the widget allows the NRDC to quantify ROI in its social efforts.

To promote the widget, the NRDC is packaging it with musicians who post it on their websites.

The October 22 launch of the widget was kicked off with an email, sent out to musician KT Tunstall’s opt-in list. Anyone who installs the widget by November 26 will be entered to win a guitar signed by Tunstall.
