Newbie to Mastodon here. I read that Mastodon has thousands of instances. But when I go to the Mastodon page (https://joinmastodon.org/servers https://joinmastodon.org/servers), it lists only 40. And there's no search function, so I can't find an instance that I know exists because I already have an account on it (mastodon.online). (I want to open a second account on the same server.) What's the deal with that? How can I navigate to a server I know exists but which isn't shown? When I navigate to mastodon.online on my browser, there's a "Create account button", but that just takes me to the Mastodon page I'm talking about.
