I'd like to start with the @promo-mentors community.
This one is a project lead by @futurethinker which caters newbie and veteran steemians on the platform.
It's main goal is to improve the experience of steemians here and retain the members by creating a small community of diverse people across the globe that is willing to help and provide feedback on their post.

One of the most awesome feats of the @promo-mentors are we have some folks that are connected with Curie and OCD which provide workshop sessions to the members in that way they will know the ropes on blogging and stuff. From poetry to science articles we have mentors that can help them improve plus a hang-out place where they can mingle with other people too.

I do support the project of @steemitfamilyph I am one of the members there too and I saw how each one of the folks got transformed and inspired on the projects and mentorship that is ongoing.

We are a small group of bloggers for now but the impact that we are doing is awesome. It does matter because with the support that we are able to give to the newbies we make them stay on this community. Our community vote doesn't weigh that much right now just a few cents but the bonding and camaraderie that it gives to all folks in here is solid. We are also inclusive to all folks that are willing to be helped. We are here to help retain folks which can help the steem community by delivering quality works.
