Hiya! 
Episode is (kind of) testing the waters of an adult version of their app, called Ivy. There have been a couple threads about it.
It’s definitely a work in progress at the moment; I’m pretty sure it’s only available to iPhone users in Australia or an equally small group, and it doesn’t have a writer’s portal.
I’m definitely holding on to hope that they see that project through; not only do I think my stories would push the envelope of the guidelines, but I’m not sure I think 13-year-olds would or should read my in-progress story lol.
