I went to infastructure mode to play online and it says enter a password but I never was asked to enter a password when I started to play the game on my psp so what password is it asking for and or how do I set up a password?

The prompt should be asking you to enter a new password, so think up a password and enter it.

Someone else may have already taken that name. It would tell you if it was in use after you tried to enter a new password. If that is the case, you need to go to your profile and change the name.

If you haven't been on-line, you can rename your profile. Profiles->Edit profile->[your profile name]. Enter a new name. Sign in to WormNet. (A hideous palaver, sorry.)

The name is only locked after you've successfully signed in to WormNet.

I was hoping I could correct my mistake before someone noticed it/replied. I thought you couldn't rename your profile but then I tested it on an account that I hadn't used online before and I was able to rename it. Good to know.

Phew. Thanks for the confirmation there: I was getting worried that the system was bugged and wouldn't let you change the name at all.
