mods?

[I_DONT_CARE]

This is my first post (so if I put it in the wrong place just tell me) anyway I have a few questions about mods. First when I look for more Dramatic mods all i find are ones that aren't finished, So are there any web sites I can get some big mods from? Second any idea how I could make a mod for Massive Planetary armor (like Massive Planetary Shield Generator) there Wouldn�t Really be armor all over the planet but more in Strategic places (citys and Military stuff) anyway if you could help me out it would be great.
