What is LID?

I've been asked by several now "what is LID?".

I copied this from another blog...

LID stands for “Logged In Date” and it is the date that China confirms the following:
1. Received the dossier
2. The dossier is complete to their standards - VERY IMPORTANT!
3. We’re now on the waiting list to have a child assigned to us!!!

Still no word on our LID.
