It’s almost been one year (August 2013) since Linden Lab updated section 2.3 of their Terms of Service and today the lab have updated it regarding user content in Second Life. This small change is a positive step moving forward I think and please see below for the new updated TOS highlighted in blue.
New Section 2.3 as of 16th July 2014
Except as otherwise described in any Additional Terms (such as a contest’s official rules) which will govern the submission of your User Content, you hereby grant to Linden Lab, and you agree to grant to Linden Lab, the non-exclusive, unrestricted, unconditional, unlimited, worldwide, irrevocable, perpetual, and cost-free right and license to use, copy, record, distribute, reproduce, disclose, modify, display, publicly perform, transmit, publish, broadcast, translate, make derivative works of, and sell, re-sell or sublicense (through multiple levels)(with respect to Second Life, Inworld or otherwise on the Service as permitted by you through your interactions with the Service), and otherwise exploit in any manner whatsoever, all or any portion of your User Content (and derivative works thereof), for any purpose whatsoever in all formats, on or through any media, software, formula, or medium now known or hereafter developed, and with any technology or devices now known or hereafter developed, and to advertise, market, and promote the same. You agree that the license includes the right to copy, analyze and use any of your Content as Linden Lab may deem necessary or desirable for purposes of debugging, testing, or providing support or development services in connection with the Service and future improvements to the Service. The license granted in this Section 2.3 is referred to as the “Service Content License.”

The next time you log into Second Life, you will have to agree to the updated Terms of Service (section 2.3).
