How are you looking to differentiate this new tribe from the others? Do you have a particular theme you’d like to follow (or to avoid)? Having specific goals or topics for the community to rally around will help attract those you hope to share your vision with. Maybe start with the inspiration for the name of the tribe :).

Articulate what is good content to you will help - everyone thinks their content is great, even if it is horrendous in the eyes of most. Do you have a list of tags that would represent the types content you hope to see? I hope this helps!
