Why are there only two categories of divination?
 

Why are the only listed categories for divination "pendulums/dowsing" and "numerology, runes, etc"??
I can understand pendulums/dowsing being a category, but why are runes and numerology combined? Not to mention everything else. There's not even obvious mention of tea reading, palmistry, bone reading, scrying or even a category for tarot and other things that would be categorized under cartomancy. I was hoping I'd be able to find a space to discuss runes and even some of the more obscure types of divination, but there isn't even a discussion space for the more common, every day forms.
I'm very very new here, so I don't mean to sound like I'm hating on anyone. I'm just curious if it would be welcomed or even allowed for me to begin creating other categories? And I'd obviously be happy to start discussions in those categories.

Just make a new topic like you did this one in the divination section 😊
