It looks like there are many more MMM plugins than referenced here ( http://devnull.sweetdanger.net/fcomloadorderexpanded.html ). Should I not install any mod not mentioned there?
If there's an http://www.gamesas.com/index.php?/topic/1085113-relz-fcom-convergence-and-ufcom-relz/ for a mod the general idea is to thoroughly read the readme and then post questions in that thread if your having issues.
Starting independent threads leads to well intentioned, but often misleading and confusing information.
If you want clear instructions with any mod the official thread is the place to ask.
It's where modders and those familiar with that particular mod tend to hang out and your question will normally be answered in one post.
