Have no clue how to play online

[Luc@s]

I need help I saw a thread that had some what of the same problem but not really.
When I go to multiplayer on Assault Cube it shows for options I choose join server, then it shows ping, plr, server then help/settings. I couldn't find the help on google so I'm asking what do I do to play online from there?

Make sure you are running the latest version of the game
(1.2.0.2)
