I kinda dropped the ball with the Colossal Castle Contest this year, not announcing the custom minifig categories until late in the game. I plan to rectify that with Forbidden Cove's Jolly Roger II Contest.
There's lot of categories for vignettes and ship building, but BrickArms is sponsoring a custom minifig category for Pirates of the Caribbean. You can see all of the contest categories here.
So hoist the colors mateys and get ta buildin'. You have until March 15th, 2011 to submit your entries.
