This server keeps a copy of my SSB feed, synced frequently, and allows you to fetch it too. You can find the invite code below.
Note that syncing with my mirror means you get my data, but I won't get yours, so it is unlikely I will see your comments and likes on my posts. For reciprocal communication, we would have to sync with the same Pub server, or I would have to sync with your mirror server. Learn how to setup your own mirror here.
