This document provides suggestions for how to participate in Wikipedia's 10th anniversary celebration, which takes place on January 15th, 2011. It encourages Wikipedians to use the official 10th anniversary mark - which features the number 10 in different shapes, colors and puzzles representing Wikipedia's multilingual nature. It also suggests asking others what Wikipedia means to them, sharing one's own experiences, and spreading awareness of Wikipedia's accomplishments as the largest collaborative team project in history.
