As I told you, make sure you read the whole introduction to what Steemit is all about before posting. for the moment, just start with that and do the voting. this way, you will learn from seeing what works and what doesn't work here on this platform. Talk to you very soon! Maybe you can write your argumentative text or your Christmas tale accompanied by a few pictures!?! Don't forget to let us know where the pictures come from, especially if they are not yours!!!)

Namaste :)
