http://www.weidu.org/ this site was given
some were cant remeber and they said
you could download extra NPC's but were
and also how do i install them?

This site is still in progress. Before that it was on www.cs.berekly.com/weidu if i recall right. The important thing is,it was Weimer if you are more familiar with this name.

Go to the other mods section, their is a fairly complete list of all weiDU based mods there. To install them, just unzip them to your BG2 folder, and run the setup exe that comes with the package.

One thing though, if you run your multiplayer game while having those mods installed, things might go a little weird, since your computer will have different scripts than all the others.

ah okay that may cause some problems then :s
