Welcome to Steemit and best wishes for success in teaching and with Steemit. Learn the Steemit way and you will prosper. Early advice for success is to upvote others that comment on your post (those worthy of an upvote of course). While you have not much voting power for rewards, your vote helps build reputation for others, and that holds value in and of itself. Good luck.
Thank you for the welcome and the informatios :) I will not forget those
