Virt, that is the same program I use, I'm guessing you got the idea from the coments on my video? But, on to my point, I most likely will not make a guide on how to edit md2s, but if you ask me a direct question, I'll answer it for you. One thing that I learned fast is that if you want to add something to a model without changeing the animation you need to use "MERGE." In witch case you need to have the thing(s) you want added in another file.
