Items missing information
Show items missing information - This will run a special search that has a new set of filters down on the left. These filters can be used to filter the search results by items that are missing certain pieces of data. Several of the data types will only apply to certain items, for example lip colour will only apply to items with lips.

The inventory for recent sets is automatically imported from LEGO. Older sets and minifigures need to have their inventory created manually. To create an inventory for an item, go to the item, click on the edit tab, and then click the create inventory button.
When new sets are created, the parts of a Minifigure automatically added, but these need to be assembled in the figures. You can click on the link from a set inventory to go to the Minifigure creation form which speeds up the process
