I've been adding some mods to FO3 lately and got to thinking about doing some on my own(just armor and item stat mods) so I spent around 2hrs looking for any threads on it and finally came across one that was similar to what I was wanting to do.
The threads' only useful response was "look at a this tut here's a link" so I click on the link, it's dead

so I try to find some tuts all I find are ones for doing textures and meshes *sigh* I'll have to make a thread and see if I can get an answer or at least a working link.
