Welcome @lauralauze !! I won't go over the same thing so many have already told you, but, I did want to reach out and welcome you!I am glad you made the jump, I think you will like it here! I reluctantly came four years ago, to Steemit, before it forked over and have never left. :)

Check out the different Communities and find what fits. I was surprised that I found some that aren't who I would find intereting, and yet... I do.

Again, welcome! So glad to have you here!
