To confirm what Shurtle said, it is pretty hard to find non-literate roleplays. Most of them are literate, if not semi-literate. Atleast when I'm in Flourite, that's what I've seen. Try searching around the forums for groups that are advertising if you haven't already.
If you can't find anything, I'd highly suggest making your own group. That way you can make your own rules and have the roleplay you're looking for. That's all the advice I can give ya. Good luck though. c:
