Thank you for stopping by. SMT's are Smart Media Tokens. From what I understand, communities on steemit will be able to create their own coins backed by the steem blockchain. This will enable communities to pool resources together and create their own currency within the blockchain.

I do not know how it will work.

Discord is not connected to steemit or steem, it is a service that many of us prefer to use. You get your own address when you sign up. You find communities by finding their links which are usually embedded in their banners or next to their avatar.

If you want to link something you use [inside here go the words you want to use](inside here you put the link you want people to follow).
