So on the top right hand side of your screen is your avatar, click that and it'll display your top tribes. You can click show all from there and the page that you're redirected to will have options to see the top tribes on the site, and up and coming tribes. You can also search for specific tribes using the search feature and there is a /t/newtribes to check out what people are setting up.
There is a limit to the number of tribes that you can join that gradually increases with your user levels and rankings though I don't know exactly what gets unlocked and at which level.
