LMB Eternal (LMBE) is a project started by Astrokid12, Helios, Keplers, and TopSecretSpyGuy. The goal of LMBE is to continue the LEGO Message Boards (LMBs) which lego.com hosted for several years. LMBE also hosted an archival effort for the LMBs, which is currently still being put together due to the incredible number of topics submitted to the archives.
The name of LMBE is not "LEGO Message Boards Eternal", but is actually just LMB Eternal. This is to prevent issues with copyright. However, most users call it "LEGO Message Boards Eternal" out of habit.
