Login Sequence

1. Login (107): Client sends credentials and Version (160).
2. Show Agreement (109): Server sends agreement text.
3. Agreed (121): Client acknowledges acceptance.
4. Get User Name List (300): Client requests the global user list.
5. Post-Login: Client requests File List (200) or News Categories (370).

Legacy Login (Version < 151)

If the server version is below 151, the Agreement phase is skipped. The client immediately sends Set Client User Info (304) followed by Get User Name List (300).
