Start by making a post in the Clan section of the forums saying your clan name, how to join, and showing some builds! Name: BE creative! I did Eco-Be. Elite Crew (of) Organic Building (and) Eventing. The name also comes from every member who joins gets a real life tree planted with there name by the roots. How to join: Is your clan a building clan? Make someone apply with a build with over 1000 bricks! Eventing? Have someone make a build with over 20 events! Stunts? Make them make a 60-second blockland stunt show! Good Builds: Check my new topic soon for good builds, but dont be spammy, make it with good colors, and Also, Make an HQ! This is where your clan comes together to discuss upcoming projects, and where they come to accept new members to the clan!
Hope this helps!
