Welcome to the Steem World!
I have recently made an orientation video that will help you in your journey here - and will hopefully answer all the questions that took me months to figure out.

I wish you all the best here on Steem!
Wow! Thank you for letting me know about your introductory videos. I actually had no idea Dtube existed. I think I'll start uploading my dance videos through that rather than Youtube!
