Moving bones to another model

As the topic says how do I move bones from one model to another model. And another question do i have to attach the bones to the model ?

u mean 3dsmax edition or mdl edition???
If u mean 3dsmax, I use vertion 5, n do it thankz to Cookie´s tutorial on importing models.
If u want to add a bone from other model simply import that model as well then delete the bones n mesh u dont need. :)
If u want to add a bone just create an object(like a cube or ssphere with 4 or 5 sides)(or u can use max bones(which I dont know how to use)) mark it as bone in the "user property editor" n link the "bone u just created" to the original bone which u want to be the parent.
