I was very confused at this “non-LN book clubs”, until I realized it means Learn Natively and not Light Novel 
All the clubs under the Informal category are fully hosted here on Natively.
In the case of きらきらひかる, it is loosely part of a WK umbrella club, in that it lists books of certain characteristics (“profoundly weird” protagonists), with links to whatever reading thread is created. So there’s a link there that links to the thread here. It’s not an official club or anything. We can remove the link back from the table if you think it’s cleaner.
In the case of リング, the connection is even looser. It was nominated in the Halloween club in WK, but didn’t get any votes, so I made a thread for it here. It’s fully a Natively club, but it has its origins in WK so to speak. Again, the link can be removed from the table. I really don’t mind either way.
Or we could add an (ext) next to the links to show the link to the parent club is external. Or WK. Personally, anything that brings more books to my attention is welcome.
