Additional: You can't minimize the game only if you have a program for it, I use this: http://ultra-utility.com/
Download and install it then go to Navigation->Hotkey Assignment and assign a hotkey for the minimize feature.
To join the Roleplay you go to the "Galactic Register", review the form and create a character based on that form.
