It's been a while since I've modded (I've been a member of these forums for a while but I couldn't remember my past login information), and my last bout was with Oblivion where I ran into a huge graphical issue I couldn't solve so I put it on the backburner for a while.
However, since I got Skyrim the other day and have been looking into modding it, I ran across the NMM which seems to be an amazingly easy tool to use for modding.
My question is, I noticed that you can use other games with it as well. Does that mean that I can use it with Oblivion and Morrowind as well and easily mod the both of them, including big mods such as the Morrowind Graphics Extender, or OOO and such?
Thank you for any help!

It will make troubleshooting much easier should problems arise.
