What is TDD and where can I get it?

[Valagaar]

I have looked all around a ton of posts and have come across something called TDD...as I have come to understand it as a very large upgrade for BG2. If that is what it is where can I get it? I havent seen one like anywere.
(sorry if this seems stupid... )

TDD stands for The Darkest Day. Its an add on. You can get new quests new npcs new items, the works.
Most of the new areas are made using old maps from BG and BG2, but don't let that get in the way of your excitement. Its still a lot of fun.
There are also alot of bugs. Downlaod their patches(one so far) and check the TDD forums. You can find out where you can get some of the new quests there. Also you may need to often Cheat characters vital to the story line in.

Here it is- TDD

It also takes a little while to download. I heard some people with slow connection days. Ahhhh the joys of cable
