In the modification tool of your Chronicle you can update the settings you provided in the Creation process. You also can determine which Character Types you allow into your World of Darkness Chronicle. This is based on the Type (oWoD, nWoD) you chose when creating the game. Due to integrity constraints it is currently not possible to change the type of your Chronicle.
In addition to the above, the modification page is also where you see the applicants information. For more information on the applicants, see this wiki.
