You should be able to generate an invite link to add people to your Mastodon server, and then send that to them via Signal or text or whatever.
@skyfaller oh thanks. seems like invite people is now turned off on here....
@joyfulcarla Then sadly I guess your options are to talk to your admins about re-enabling invites, or to navigate coaxing your friends on to other servers, which I know adds complexity to joining fedi. But one strength of fedi is that people can still join even if your server isn't accepting signups!
