There's the Couples & Shipping channel for romantic ship clubs, but no similar channel for clubs dedicated to fictional families, friendships or any other kind of relationship. At the moment I'd just put such a club in the Characters channel, but they get a bit lost there in the midst of all the clubs for actual characters. I suspect it'd be a lot of work to create a new channel though, and you probably couldn't easily reassign existing clubs.

I've never seen the C&S channel as exclusively romantic... you can love a couple of friends or a bro-mantic relationship. Then again, I've never put much thought into this because I'm not generally a shipper, so *shrug*.

^I think that the terms "couple" and "shipping" are so commonly interpreted as romantic that the clubs would be interpreted that way, especially in cases where some fans ship the characters romantically but others only like their friendship.

What do I know, I had a medal in a ship spot for years before I realized it had been created with romantic intentions. They were cops, I thought they were great partners! XD

I think, mostly the category for the pairing club is... "romantic relationship" but there are siblings, family or friendship clubs exist.
