Go to www.starvsstar.com, enter your username and password in the appropriate fields, and click the LOG IN button. Click GAME CENTER on the black navigational bar and click the TEAMS option from the sub-nav. Select the appropriate team from the pull-down menu and click the MODIFY TEAM button under the roster listing of your current team. On the MODIFY TEAM page, click the boxes next to the star you want to drop and the star you want to add. You must select the same number of stars to drop and to add. Click the SAVE MY CHANGES button to save your new roster of stars for the next day’s lineup. No, roster changes are free. There is no daily or weekly limit to the number of roster changes you can make. You may change any or all of the celebrities on your team roster every day by 12 Midnight ET to be effective the following day. Changes made by 12 Midnight ET each day are effective for the following day. If a celebrity is not listed in any of the four categories, that celebrity cannot be used in the Contest. Your 10-celebrity roster will carry over from day to day if you do not make any changes. Only one team in a league can have a celebrity on a given day. However, up to 7 teams in an 8-team league could have the same celebrity in the same week but not on the same day. No, there is no trading between teams.
