YES - I want to participate in the Winter '10 Sandbox Preview and access all the great new features of Winter '10 beginning September 18th 2009, prior to the upgrade of my production instance in October.

The specific server your Sandbox is stored on will determine your Sandbox experience during the Sandbox Preview Window, including whether your Sandbox instance will participate in the Winter '10 Preview. The Sandbox Preview Window is scheduled for September 18th, 2009 through October 10th, 2009.

There are two quick steps to ensure your participation in the Winter '10 Preview on your Sandbox instance:

1. Determine which Sandbox server you are on. Log into your Sandbox at test.salesforce.com; then examine the URL in your browser address bar.





2. Repeat Step 1 for any additional Sandbox instances you may have.
