Brickipedia:Official Friends
From Brickipedia, the LEGO Wiki
Below are Brickipedia's current Official Friends:
Custom Lego Wiki
When Brickipedia decided to restrict its content to official LEGO-related content, it was also voted to create a wiki for all things related to custom creations. On June 22, 2009, the Custom Lego Wiki was created, led by Lcawte as bureaucrat and founder with Coupon11 as administrator. So if you're looking for a custom set, organization or minifigure, or wanting to create an article about a custom, head over to the Custom Lego Wiki!
Wikianswers LEGO
Wikianswers LEGO began on November 25, 2009, and is a Wiki dedicated to answering all of your LEGO questions. It is a LEGO Wikia-wide project, which currently involves 7 LEGO-based wikis.
