When I started in Steemit 2 years ago there were a bunch of people helping the newcomers that introduced themselves at #introduceyourself, now I don´t see it very often. I know a spanish community that is resposible of bringing a lot of spanish-speaking newcomers and teaching them the basics, them they teach how to introduceyourself, markdown and they answer your doubts or any question on discord.

So I nominate @mayvil of @mayvileros to be a Steem Greeter

There´re some good application already in the comments :) oh, and thank you for mentioning the spanish new game development community, much appreciated.
