Hi @aviyaytor. Welcome to STEEM! The best things to do are firstly search for what you are interested in in the search button top right. Also, there are STEEM FAQs that you can read.

The next thing is to join Discord, which is the chat server that most STEEMIANS use. There are many communities there, so depending what you are interested in, you'll find invites to Discord communities as you go around Steem posts.

A great way to learn the ropes is to follow accounts that you are interested in and then comment if you have anything to add to their posts. Sometimes you will earn for this through upvotes and it's a great way to build followers up as well.

Here is an invite to join the DTube Discord, where the moderators will help you with your questions :)

Have fun!!
