Enter by adding or improving a game page using the 'Edit' link on the game page. You can also make a post or comment in the forum just like last week and enter to win a $60 board game by Tuesday 3/12, 4pm PST. Each improvement, post or comment is another entry.
Full rules here.
I'm hoping to encourage improvement to the database while also keeping the community active with this giveaway. Also, the contest start period is the moment yesterday's ended so that any potential posts weren't made in vain!
