I wonder if this is the same Exnem I know from the Oblivion modding community. It's a little weird when fandoms strt mixing like that

Yes, it IS the same Exnem. There's been some discussion about it, including here at PMBD, about how the Oblivion community would laugh if Exnem started charging for mods.
Yep. Exnem is huge in the Oblivion community. So is Enayla's textures. I have even seen a peggy hair or two pop up as well. Kinda shocked me when I first saw them, because all I could think of was "Argh! My sims! Must play!"
