As of Version 1.1.2 you can now customise the two profile fields for Players.
In the Sports Ladder Control Panel click on the "Options" button.
In the General tab you can edit Custom Profile Field #1 and #2 to whatever value you like.
In the Permissions tab you can also now control user access to various functions within Sports Ladder. For example you can restrict which user groups has the ability to create, edit or delete entries. This is a pre-currsor to integrating Sports Ladder more closely with the Joomla! user system.
