I keep forgetting to do this but I finally have.
More questions

Do you want the hair binned as brown, with a brown elder stage (ie. so it appears for both adults and elders) or do you just want a brown elder stage sitting in the custom bin so I should remove the adult stage? Just wondering, before I go to the trouble of binning and removing unneeded textures. While I'm at it, do you want the other colours done, too, or just the brown?
