Please see my page, https://www.momsinmotion.com/join-a-tribe/
Scroll down until you see the list of Tribes Near You and Tribes coming soon.
I'd like to come up with a better way to search and select the Tribe in your community or nearby, as I plan to continue adding new Tribes each week, and this list like I currently have it will become difficult to find your local Tribe. I am open to ideas, and whatever Plugin I could easily use to just categorize Tribes by State, and then have someone select a State and all the Tribes in that State would be able to be selected. Or something similar to this idea.
