@terminallyill has an entire post linked to that does a good job covering his efforts with @greetersguild & @breakthecycle.

@simplymike helps out new members with @newbiegames and there is a discord room for it also.

@lynncoyle1 might be one of the most undervalued steemians around. She helps with SO many discord groups that are working to help the smallest members of steemit grow that I can't even start to list them. Plus she has been a judge for PIF from the beginning giving out a huge majority of her voting power each week to support plankton and minnows.
