I'm kinda semi new to modding and I was wondering if it is needed to use a leveled list merger on .esm files that I have. the mods I have with these are MCA and morrowind advanced i believe. If it is needed, would you kindly point me towards a program to do this? Horatio's tool does not seem to do .esm files. please dont get all mad if this sounds all noobish. All help is welcome.

Thanks in advance
