Is it even possible if I could create a league? If so, how? If you happen to know how, post the video in your reply please.

Well, basically if you want to create a league, you go into the LFS Racing/Leagues & Events section and start a new thread where you present your league, ideally with a detailed calendar. Next you hope that people (sign-up and) show up. Additionally you can add your league to the LFS calendar by going to www.lfs.net/leagues and click on the "Add your league" button.

Thank you.

Before I forget, you need to provide infrastructure: A server for the league to take place, a (basic) ruleset.

EDIT: You also need to promote your league so people know it is happening. Social media is a place you can get people from (twitter, facebook, youtube)
