Can i set up myspace but with a different email I mean would people know my email if i wrote to them

Nope; when you message via Myspace, it doesn't really involve email, unless you activate the notification email service for message/comment alerts.

But if you want to just change your email address for your current Myspace account [not sure it that's what you're asking], you go to Account Settings and in the yellow field where your email address is displayed you simply click in there and type in the new address, clicking Change afterwards. You don't need to sign up for a new account.

are you asking if you can create another account, using a different email addy would someone be able to tell that it's from you? the answer to that ? would be kinda. Your IP addy can be tracked so you would need to use a different computer for each account to be super steathly!

The long way people would know your e-mail on myspace is if you tell them or pit in your profile/blog. My space uses there own system for sending messages to people within there website which doesn't use you e-mail.
