Codemasters has announced today a special Welcome Back Week for Lord of the Rings Online players. From February 2nd through February 9th, they're inviting players to come back and try the again game for free. This only applies to those who have tried the game previously, and let their game time expire. Also, as far as we can tell, since this is through Codemasters, it only applies to the European servers.
During this Welcome Back Week, monsters may drop special rare items that can be exchanged for gift boxes containing helpful in-game items. There will also be a Great Musician, a Great Fishing Tournament and a Fashion Maven in game. You can read more information at the Codemasters forum.
[Update] It has been confirmed to only apply to the Codemasters/EU servers
