Hi, @fortheloveofgrace7! Welcome to the PBC!
First, I'll address boards in general - then I'll address "group boards."
Boards are sort of like file folders for your ideas on Pinterest.
You create them and then add pins to them. You can save other people's pins to them, and you can create your own pins and put them in there.
Most creators and marketers think of them as similar to your "content pillars."
I recommend that clients and students do keyword research in the space that they are creating - and then create boards for each of their main content pillars based on those keywords.
When you create a board, you can give it a name and a description. If you're ready to be very strategic, you can make sure those are keyword-rich. (But make them readable for humans, so write sentences in the description that describe what you pin there - but don't "keyword stuff." i.e. don't simply list keywords.)
In my opinion, your first priority should be to create and optimize your OWN boards.
You do have the ability to add other creators to your boards. And you can be invited to other peoples' boards. These are commonly called "Group boards."
But keep this in mind: Using group boards to try to increase your reach or traffic is considered by most Pinterest experts (me included) to be an *outdated* strategy.
I strongly believe that it's better to spend your time and energy creating and organizing your OWN boards and content. You want to be focus on creating an account and pins that are helpful and inspiring for YOUR target audience and showcase your own ideas.
I hope this helps you get started!
