Because you have the number "7" after the keyword "password", IOS is 
expecting an obfuscated (encrypted is too strong a word here) password 
to follow.  You have supplied a plaintext password.  Try:

    username peter privilege 15 password peterpassword

Or for more security if your IOS supports it:

    username peter privilege 15 secret peterpassword

Yes, if you're configuring remotely, you can type:

     reload in 30

which tells the router to reload in 30 minutes.  Then make your 
configuration changes.  If you lock yourself out, the changes won't be 
written to memory and when the timer expires you can get back in with 
the old configuration.  If you are successful in modifying the 
configuration without locking yourself out, after saving your changes type:

     reload cancel

to stop the countdown and cancel the reload process.
