When I run the Administrator Client, I get this screen:

Notice that I have already used this application, and it remembers I used port number 9999. If I click on 'connect', I get this dialog:

In here, I can input the host, port, login name and password to connect to the Xelagot Server. In this case, host is "localhost" because I have the server on my own computer, but normally it would look something like this: "14.210.7.49", or like this: "auth.myserver.com" (without quotes). When I hit 'accept', if the server is online, I get connected...

Online are AlphaBitToe (bot), Creep (bot), Delph (master, a bot with extended privileges) and possibly others down the list, including myself, who logged in as Xelag A (administrator). A right click on Artista....

and then on 'edit client', gives this:

See, the login name is grayed out, so it can not be changed in edit mode. Other fields can be modified online. Artista is a User, a person who owns 2 bots on this server: they are assigned to her in the 'user bots' field. If she would log in now, using the User Client, she would see this:

When you modify an entry of a client, and the client is online, it is requested to automatically log back in, so that updates get properly propagated to all clients (version 1.0 did not do this). If you delete a client, it gets expelled if it is online.

Adding new entries to the server database and deleting entries is just as easy...
