Welcome to MFN, thecraftyone! I hope you enjoy the game. My advice is to start slowly, until you get the hang of the game and then add a couple more teams when you get familiar with all the aspects of the game.
Something else, don't be afraid to ask questions. Many of the MFN owners are quick to help and have a ton of knowledge about the game.
I am in quite a few leagues and thought I would share some of my favorites if you would like to join any of these:
MFN-10 - 6 teams available - This league has experienced owners and is very competitive.
https://cust10.myfootballnow.com/MFN-20 - 5 teams available - including Carolina...you get to face me. This was my first league.
https://mfn20.myfootballnow.com/Fake Pigskin - 9 teams available - Would like to see this league full!
https://fakepigskin.myfootballnow.com/Custom 62 - 9 teams available - Just joined this league. Love it!
https://cust62.myfootballnow.com/MFN 83 - 1 team available - Younger league...my first allocation draft league.
https://mfn83.myfootballnow.com/Those are just a few. Many more really good leagues. If you have any questions, feel free to pm me or put your questions on the community forum.
Good luck!
