Ah, then your guild leaders are @Tinker and @Viviane, feel free to message them or any of us @Wagoneers for assistance. Once you’ve been active on the forum for a few hours you’ll be able to access the guild page where you can introduce yourself to your new guildmates and learn what it means to be a Flinterforged.
Also, if you open the menu (three lines at the top by your icon) and go to “groups” you can officially join your guild on the forum, that way it will show up along with your name.
