Do you know?

This is mostly for Melinda. As I was reading through stuff trying to set up my own blog I think I read something about there being a way to have multiple authors that can post on a single blog that way we could all just sign in with our own username and password and it would show who actually posted and everything wouldn't be from Melinda.:) Do you know anything about this or how we could set it up or would you mind if I did? (or tried to:)) Maybe it would help-or maybe not-let me know. (This is Jana by the way!)
