I think I just did. 😬 see if you can search for the Nostriches tribe (small chest mid-bottom right on the screen).
It won’t let me lower the minimum level, so you’ll have to be at least at 10 to join.

Thanks! I am working my way to level 10. My power has been out all day and my data was not working so have not had the time to get on here today. The power just turned back on. I am checking it out now.
If it’s still maxed out (10/10) when you’re ready, send an in-game request to join and I’ll make room for you. I made it Public when I created it and it filled up immediately (?!). Pretty sure none of them are nostriches, so you will have priority. :) Hope your power stays with you.

I didnt even see the name last time I looked. I had so much going on. Our tribe name is awesome!
