"You have closed registrations on mastodon.social, so how will my friends get in or find me?"
Tell your friends to sign up on https://knzk.me/about then tell them: "Search for MyUsername@mastodon.social" and voilà, you have found each other.
It's very similar to how e-mail addresses work.
@XavierJulep @Gargron That worked to help me match followers in the domain I signed up with, but I know there are people who had to go into another domain (instance?). Am I missing something? (The one that I know is in a different domain, I'd already followed before trying this, though. So maybe it did check for others and didn't find any more?)
This Mastodon instance is for people interested in technology. Discussions aren't limited to technology, because tech folks shouldn't be limited to technology either!
