I've not heard of Quotev, sorry. I'm more of a "fanfiction.net" and "Friendship is Magic Fiction.net" kind of guy. And even then, I only browse those places, not write stories for them
Even though I've made it abundantly clear that I'm very much capable of writing actual stories if I ever wanted to
But yeah, Starting a Klonoa group on there might be fun. Heck, it could even help bring in new forum-goers!
