Just want to chime in with, this does feel very slick, but this was the #1 question I had. I could not determine it from your site, and had to try it out to see.

One major criticism of things like Discord is that they're private, so I don't think that it's inherently disqualifying, some people might even prefer it for that reason. But it's very, very important that you're very clear about this, up front.
