You can talk about Adventure Time all over the internet, 4chan, reddit, the fan club, our forums, facebook(?). Discussion isn't limited to just here.

No I meant on the other wikias I've downloaded there is no discussion section, and I'm wondering if the at wikia app is the only one that got one?

I downloaded 2 other wikias and both have no discussions

I downloaded the wikia before and disliked its structure, episodes weren't listed chronologically. About discussions, I personally see blog post and forums as a better way to talk.

There are other different Wikias with Discussions.

There are other wikias with discussions but not all of them, for instance I had Pokemon wikia and didn't have discussions but now it does
