And good job for this plugin. You will be glad to know that your plugin could become one of the most popular doing team management on WordPress :)
I use it to manage Online gaming team on two games : Counter Strike and Battlefield.
I had to modify some code to make the admin panel more appropriate to this usage.
Today, I'd like to create 2 new format as your baseball_college or baseball_pro.
But I don't manage to understand how to add this. (I'm aware that it's needed to code a little bit, and there is no probleme with that).
Do I only have to modify the mstw_tr_set_fields_by_format function ?
By the way, i'm sure you plugin can become a big an easy plug for general purpose as you code it in a really simple and efficient way.
Maybe some new feature could make it umbelievable : make the plugin able to use wp_users informations to make players registration. Player pages could become the user public profil :) and other intergration stuff.
Thanks for your answer, and of course, your plugin.
