We won't be adding in any messaging options within the app for users to contact one another directly.
At some point after release, though, we will be adding in the ability for users to ask questions about sentences within the app (and answer other users' questions).
We will also have staff native speakers who will be enlisting to help moderate those questions and answers, marking the best answers from the community, so you know which answers to trust.
We know it isn't quite the same as sharing a gif or meme in your target language with your new learning buddy, but we want to keep the focus on learning while you're using the app. Especially since there are any number of platforms available for contacting other learners (Fluent forever forum, the Facebook group, etc).
You WILL survive this. We promise.
