Yeah it's from the Nexus, mine looks similar too.

As for the poll, I use around 10 mods in each Beth game.

tried fallout 3 finally,did put an bodymod in there,on the other hand I didn′t got hooked so it is pointless.

morrowind,well I like outfits for my char and npc′s I drag home,so I have a few of that kind of mods,besides ordinary stuff,including merges to fit them all.

oblivion,well basically everything needs to change there so I tried, partial success
ahh yes,200+ mods in both games,and one mod in fallout 3.
