I think so... I am still trying to figure it out. But when I go to the other instance (which I used before this one) I couldn't find this place in Search at first, and now I found it but the comments weren't loaded. So it maybe seems that the "one account for the entire Fediverse" thing is a lie lol.

Works for me! Availability of other nodes might be a big downside of Fediverse though.
