I got a really good one that I've seen everywhere but most people read summaries of it at best.

How To Win Friends and Influence People

Here's a server invite for a discord dedicated mostly to new players and helping players make groups together. They also offer free classes on various things from the basics to more advanced things.

Also as a disclaimer, this is not my server nor am I affiliated with it at all. I just really enjoy what the people over there do.
