Welcome to Steemit dirkboy41. Let me know if you got any questions about Steem/Steemit. The official FAQ can be found here and is quite extensive https://steemit.com/faq.html - Also, Steemit is just one of the sites using Steem the blockchain. We also have Dtube, Dsound and Steepshot if you prefer videos,music or pictures instead of blogging content. And many more of course!
Thanks for the info @janne! I've dabbled into dtube but not the rest. So much to check out! Any good sources to learn more about all the different apps?
