This is NOT a new league. We started in 2006 (?) and are in season 2016. We use OOTP 6.5
Let me start off by explaining the concept, as I have came across a lot of people who don't know what a true players' league is. We use FICTIONAL players. But each of these fictional players, are renamed, and handled by REAL people. Like my players are Jeremy and Alex Martin, if you want to check out that site. There are tons of things you can do to upgrade your player, from posting, spending your contract money, writing short articles, or even by just showing up to the live sims via AIM!
Do I have you interested yet? If so, all you have to do is go to the site. Go to the "Create your players here" forum, and fill out the application! You can have two players to start with. Either one pitcher and one position player, or two position players. If you do that, don't forget to say that Martin recruited you.
And for those of you who love the managing aspect, we do that too! I currently am the manager of the Philadelphia Threshers. Of course not everyone can have a team. But if you come, stay active, openings will come along, and perhaps you can take over a team. As of right NOW we have one opening that we are looking to fill.
And don't forget, Martin recruited ya.
