All good! :-). If you wish to learn more about the wider fediverse, check out this page: https://fedi.tips/what-other-kinds-of-servers-are-on-the-fed...

And if that goes too deep too soon, then the home page of the same site can help provide a brief primer. Of course with the fediverse gaining recent attention (due to mastodon and pixelfed), there are plenty of other guides out there as well. Good luck!
