This isn’t an SSi initiative, but @virginia-steinkamp is very familiar with SSi methods and, as well as English, is both a Welsh and a Spanish speaker!
She has created a Facebook page offering online chats in Spanish, with sessions for both Beginners and Advanced speakers. If you’d like to push your Spanish along to a new level and get some practice of what you’ve been learning with SSi Spanish, this could be a way to do it.
Here’s her Facebook page: Spanish with Vir - Connections and Experiences for Spanish Learners
