I am all for an introduction email after having been accepted to Steemit that explains all this stuff in the native language of the person joining.
I have given people many different posts on how-to or simple guides or etiquettes... There are hundreds of posts like it... waste of precious blockchain bandwidth if you ask me.
But thanks for the very concise but accurate list: you've basically created the email I hope future New Steemians will receive upon admission.
I just today replied the same message to this post
Maybe you can combine forces and get things done for real!
Firstly, I totally agree! Such an incredible idea to have an email containing all the required information. There are Welcome and FAQ pages (I read those right after joining) but I am not sure if people read them. The environment suggests that they don't!
Thank you! You found me a gem! Wondeful post!
