Shouldn't Hermione Granger be here? she knows every question on every lesson and must be good at potion if she knew about "Polyjuice Potion" in the second year --Bongo2009 ^Talk 17:23, 10 August 2009 (UTC)

She was neither an inventor nor a teacher or someone of that kind. For the same reason, Lily Evans and Peter Pettigrew aren´t listed. What do the others think?--Rodolphus 17:31, 10 August 2009 (UTC)

I think we should define "potioneer" as someone who makes potions for a living, whether as an apothecary, researcher, or teacher. ★ Starstuff ^{(Owl me!)} 23:58, 16 August 2009 (UTC)
