Edits > Player Host Password/File Change
This is a link to a web based form to Change or Delete a players Password, EMail Address, Favorite Team and or Pools playing in.
There is a button to "Show Current Password File" to help. If a player need or wants to change their name you can have them sign up a second time and after your signup period from the web is over you can delete the old name (account). If you import players you will also import that old player again and have to delete it another time.
