I know this isn't the place to ask, but when I launch the game and I type in my username and everything and it takes me in and I click on the Team Extreme server it won't let me do anything, there are like 50 other people in a hole with me in which you can't get out of. I know you have to be logged in to get out of the hole and be able to play. I AM!!! Unless it means there is some other place you need to sign in besides the forums I don't know what to do. Please help me.
Now in answer to your question, when you type in your desired username at the beginning when you open minecraft, try and make it unique, otherwise you run the risk of that username already being taken. If the username you pick is already taken, you won't be able to do what I'm about to tell you.
Alright, now that you have selected your desired username, click on the TeamExtreme server, and it should bring you to the spawn, which is the "hole" you are talking about. Goto chat by pressing "T," and type /register (Desired Password) and then type /login (the password you typed), if you are unable to do this, (i.e. it says the username is already taken) then you will need to exit MC, and then choose a new username. Then repeat, it should work, if not, then pick a more unique username. The password you /registered with is now your permanent password, until you wish to change it. To change it, type /change pw (New password)
