The idea started because I had to come up with a way to get Pepper to use a nebulizer for medication. As I didn't think she'd be willing to wear a mask, I built a box-chamber for her, and wrote about my plans on a couple of the groups.

That same day two people with ill buns posted questions to the same group and I thought "Somebody ought to get all these people and this info in the same place". And because this is the way I think, "somebody" turns out to be "me". :)
