Enjoy the network and all it has to offer. If you are new to using Mastodon, there's a good guide here: https://lifehacker.com/a-beginner-s-guide-to-mastodon-1828503235

We also have another new users guide, posted here : https://write.tedomum.net/rgx/suggestions-and-guidelines-for-new-users-written-by-mastodon-art-administrator
