It just occurred to me to mention: since Mastodon doesn’t have advertising, check and see if the people running your instance(s) have some way to send them donations to help keep the servers running.
If you can, of course! But even a little bit now and then can help, if as many people do it as possible.
I am not actually an instance administrator or anything; I just want the lights to stay on. And my dollar a month is insufficient by itself.
