Here's the official note that LEGO made on the LEGO Factory site:

June 1st - Late Spring Gallery Cleaning

With focus on giving you and future users the best possible experience, we have decided to clean up our gallery. In this process, models older than 12 months of age will be removed. Therefore, we ask you to save your cherished creations prior to June 1st. We hope our decision won't be of any inconvenience. 

To download your old models follow these simple steps:

Log on to My LEGO Factory

1. Click on the model you would like to save.
2. Click the Download button.
3. Save your model on your computer.

- Repeat steps 1-3 for each model you'd like to keep.

   Hello, I'm new here, looks like a really cool site, my review is on LEGO's EMERALD NIGHT, kit # 10194 

Help wanted for the LEGO layout at the National Model Railroad Association (NMRA) National Train Show from 10-12 July in Hartford, CT!

The National Model Railroad Association (NMRA) is holding its annual convention at the Connecticut Convention Center in Hartford, CT from 5-12 July, 2009.  The National Train Show will occur 10-12 July, and included is a large space for a LEGO train layout.  Trains-n-Town is proud to host the planning of the 2009 event, which is a one-of-a-kind opportunity to showcase LEGO trains and the capabilities and diversity of the entire LEGO hobby.
