Name / IP: Needs to be a valid name or ip of the chosen server.
Port: There's normally no need to change this entry. There's no known server listening on another port yet.
Nickname on server: Enter your designated name on the server here. Notice that a name can only be used once at the same time on the same server.
Teamname on server: Optional. If you're playing in a team you can enter the name here. You can always change / leave / join a team through the main windows menu. Notice: In TSpec mode the teamname is used as the password.
TetriNET: You have to choose a game mode for this account. TetriNET is the standard game mode.
TetriFast: A modification of TetriNET. The block delays are removed resulting in a much faster game.
TSpec: TSpec is not a regular game mode, it's for spectating only. Only allowed on a few servers. Notice: In TSpec mode the teamname is used as the password.
Connect: Connect to the server using the specified values.
Using Quick ConnectSome people don't like the accounts or find them to difficult to use. Quick Connect provides almost the same dialog as the original client. However, Quick Connect does save the values. They will be allready filled in the next time you use Quick Connect. So if you're only using one server and one nick Quick Connect should be sufficient.
