Welcome to Steemit! glad more and more people are joining, I'm also new but have read a couple of posts that have helped me getting to know the platform better. you can start by checking this one: https://steemit.com/steemit/@mindover/steemit-for-dummies-like-me-everything-you-need-know-to-get-started , this one is from a year ago so some changes have been implemented since then, you should look information about "steemit hard fork 19", also always good to check the steemit FAQs: https://steemit.com/faq.html, let me know if you have any specific questions about the platform or STEEM in general, I'm new but trying to learn as much as I can. Good luck on your Steemit journey :)
