I've created a Discord server called "Speaking in Artificial Tongues" dedicated to speaking practice for conlangs. It's meant to be no drama and focused on speaking rather than creating conlangs. There is something of a "no natural languages outside of pedagogical purposes" rule, or at least intention. The r/conlangs Discord server already covers a lot of the text chatting in natural languages there is to be done. It's probably also meaningful to engage in in-conscript and in-conlang text chat as practice and possibly tests for conscript development, but mostly I'm trying to get fluent in toki pona and hopefully eventually others where the servers dedicated to particular conlangs mostly do voice in English and the servers devoted to conlangs in general mostly deal with construction of artlangs for fiction with little or no voice activity.
