I'm not positive but I think I've seen a mermaid discord link floating around somewhere. It might take a bit of searching before I can find it though.

Edit: My bad, I clicked on this thread from the links in the sidebar, I didn't realize it was for a specific pod. Sorry, I'm not local to you guys so I wouldn't know if there's an existing chat for you guys or not. I do recommend discord though, it's very convenient. Facebook messenger is pretty easy to use on mobile too.
