This is a great league to be a part of. It's very active, the commissioner is very fair, and the collection of GM's is great. It has really turned into more than just an online league we're in, but a community of online friends as well.
I myself was a newbie upon joining, but with the help of my fellow GM's and the methodical way the league approached getting started, I felt as though I was eased right in.
I feel the Cuban League is both a wonderful alternative to a waiting list, and a great way for inexperienced GM's to get their feet wet. You'll get to be a part of our community, develop relationships with other GM's, and of course eventually take over one of the Major League teams.
Contact the commissioner as long as there are spots available you'll certainly get your chance.
