At the moment, RCsocial.net has reached 88 local and remote users. We are making good progress. Remind your friends!
Lately the about pages (and API) showed over 100. That's because the count included suspended accounts.
A couple weeks ago SPAM bots discovered us. I took care of it but the counts were off. The latest version (2.6.4 loaded this morning) of Mastodon fixes this so the user count now reflects reality.
BTW - we passed a 1,000 messages some time ago. We now also peer with 220 other instances.
