>>1 OP Use the View all thread button before making a thread, and scroll down the list of threads until you either find the thread or not.
If a thread for a specific anime/cartoon thread does not exist, go ahead and make one, but make sure you add a synopsis of what the anime/cartoon is about, you can get one by copping one from Wikipedia or the anime website.
I suggest you remove this thread until you have looked, if you can't find the specific thread then make one with a *synopsis*.
