HOW TO CREATE A NAME:
Open the Continuum.exe and select the button "Profile"
Create a profile, fill in the blank spots :)
Most names are taken by now, since the game has been up for several years.
HOW TO ENTER A ZONE:
Highlight a zone by clicking on it. Below the zone list, theres "Play" and "Quit". Select the button that says "Play" to enter the zone.
If it says "Incorrect password for specified username" then someone else has created that name. Try a different name. :)
