Oooh, I hope someone pops in to answer your question - I just installed this mod myself, and while I'm very happy with it, I don't need to know about sims gaining skills outside my household. I tried fiddling with the notifications too and I'm still getting ones that I really don't care about - I'm more interested in Meadow Carpenter-Rhodes' surprise pregnancy and shotgun marriage to Bennie Dean than I am about Sherman Bagley gaining the logic skill, lol.
