I've tried this. I can only see the rules and archive channels, and I can't text in either of them. I just can't seem to find anything that works
you shouldn't need to type in there, scroll through the rules channel and press the green "verify" button at the bottom
if you've done that and it still doesn't work, maybe you need to pick channels to see in Browse Channels? I know Discord can be weird about that sometimes
Here's also the guide to downloading, idk whether this'll be helpful but maybe?https://docs.google.com/document/d/14YNiXcOF19doLtQRA2H2uB-aU0KaAwj-vA4IuSeD-BE/edit#heading=h.rkx1e7btmlqu
People on Chromebooks do play Clangen; there should be a version that works.
