Oh, and what you're referring to the userlist.txt with the user rules readme page. It's primary use is to sort user-created patches / mods that shouldn't be sorted in the masterlist to prevent super-bloating. Neat things can be done with it.
Ah ok, thanks for letting me know. I'll give that a whirl. I just found the masterlist.txt in the BOSS directory too. Fun.

Ah, basically to make sure the esm's are dated prior to the esm-ified esp's. That makes sense. I was getting a bit nervous there thinking that it might be changing my load order. Still, you shouldn't rely on masterupdate to set your load order...it's not exactly a load order utility. But, if it works for you....all the power.
