The allowance of non-Pokemon threads had always been a grey area. ...Let's just toss that.
First decree of the new year: threads on any non-Pokémon fandom 'shipping topic are now fully allowed. Try to make it fandom general (Glee 'ship discussion; Sherlock Holmes movie 'ship discussion; Homestuck 'ship discussion) instead of pairing general, though.
Please do note:
We are not allowing any threads based on real people--living or otherwise--unless they are fictionalized versions of themselves (such as historical people in books, video games, movies, etc). So Sengoku Basara, The Tudors, and the like, you're good to go.
That said, absolutely no threads based on board members and forum users (even if you've written about them in a highly fictionalized manner), whether here or elsewhere. Leave that for the groups.
