Please read this if you're upgrading from CommuniGator 3.0 or earlier.
Due to the new features, the structure of mailbox folders has been changed, namely:
1) 'Mail Folder" now is being created in CommuniGator application folder, it contains all other user-related folders.
2) "Mail for User" folders renamed to bare "User" folders.
3) "Sent Letters" renamed to "Sent Messages".
4) "Trash" renamed to "Mail Trash".
5) All local mailboxes now are get created in "Custom Mailboxes" folder inside "User" folder.
CG Converter application now supplied to make these updates automaticaly. You should run it once before launching CommuniGate 3.1. You should run it from the same place where CommuniGator application normally runs; it will create "Mail Folder" folder and update the contents of all "Mail for User" folders on your workstation. You won't need the "CG Converter" application after that and may erase it.
