Send one of the admins a message — they'll add you to the Realm.
Message one of these usernames
Dingleberry SMP is invite-only, so the way in is simple: ping one of the admins below on Minecraft or Discord with the same username. Tell them you want an invite and which edition you're on (Java or Bedrock). They'll add you to the Realm.

What to send them
Just so they can set you up quickly, include:
Your Minecraft username
Which edition you play — Java or Bedrock
Where they should send the invite (Minecraft friend request, Xbox gamertag, Discord, etc.)
Optional: who referred you, if anyone
What happens next
You message Xvuxs (owner) or fishyarad (mod, fastest reply).
They check you've read the rules and send the Realms invite.
You accept the invite in Minecraft — it shows up under the Realms tab in your "Friends" / "Play" menu.
You log in. Someone shows you around spawn. You start building.
First-time on the realm?
Skim the rules so you know what's up. They're short.
