Sir I'm new here and I have a few questions if you don't mind, what does it witness in steemit, how can I vote for a witness?
I'm non native English actually I don't have the courage to write a article, if I write only comments is it legal on steemit?
when I try yo upvote some time I get error message asking me to add more steem power, what does it mean?
I'm really confused can you please answer to my questions :)
