Newbie questions

Hi, sorry, I have some newbie questions:

1. bzr whoami doesn't need real email addresses does it?
   I mean, it doesn't actually send emails, it's just a
   globally unique identifier right?

2. bzr remove filename gives me an error saying the file
   isn't versioned. I had previously typed bzr init, and
   all the files in all subdirectories got added, then I
   typed bzr commit -m "version 1", which worked, so why
   can't I now remove one of those files?

Ta,
Loki
