Hello there,
I am the owner of the Crypto Empire, a community that not only serves the Steemian but also welcomes any community on the blockchain inside its sever. We have the biggest communities there and by joining us you'll be able to see a broad array of steem communities and ask about them to their representatives within the empire.
This is the best way to discover which communities to join.
You can join the crypto empire by accessing one of my posts and scrolling down to my crypto empire signature at the bottom, which has a link to join.
Cheers
Hey @spiritualmax, thank you for the recommendation! Will definitely check out Crypto Empire (:
