Fran is no longer updated, but you can find optimized versions of the BSAs in the opening post of the FCOM thread. Have you used OBMM? I was referring to making an OMOD out of MMM, such that it would be fairly simple to install.
OBMM - http://tesivpositive.animolious.com/index.php?page=obmm
OMOD Installation - http://tesivpositive.animolious.com/index.php?page=omod_installation
The installer's page has nice instructions and link for getting MMM 3.7b3 together once you know how the basics for creating an OMOD.
Thanks, but I think I'll just install it manually, just simpler for me
One more thing, can I install official mods after installing frans + OOO + MMM?
