This is a really great guide to get started. I find it specially important that you explained Witnesses and voting power. I've explained the Witness system to friends several times because you can very well spend months in Steemit without knowing you have a right to vote.
Also, I really didn't know how to manage % of upvotes, because I'm not yet at 500SP and didn't know about the slider. I didn't know how many 100% could be done daily. That really took me out of a constant confusion about how I was managing my upvotes.
I'll resteem it for my friends to see and to have it around as a resource I can send.
