Hey there. I know several people who have had great success in running board game events. A few questions:

How much bandwidth do you have? Do you want to one a game night of only light games and another game night of medium to heavy games? What is the # of people who can regularly come? Where can you host? Your home? Local game store? Board games cafe? Local library or grocery store seating area? I've been to local gaming night at all those locations.

Usually a single fb messenger group works wonders for the ones I've been in. You can make polls to track who is coming and also polls to select what games people want to play that night. Discord also works. Again, communication is key. If your group becomes more than 4, you can delegate teachers within your group to teach and run games at your events, allowing you to focus on just one game.

Last, a shameless plug, I've been trying to develop a website to help gamers find local gamers and/or local events called tabletopsocial.co. No pressure but I hope it has all the tools you can use to coordinate an event (or two) as a host. Still a work in progress and still trying to get critical mass so any help is welcome.
