Entourage is currently setup up to separate my two accounts. I would like to combine them into the same inbox. I have done this before, but cannot seem to recall how I did it. As you can tell one is a Gmail account and the other is Bellsouth (AT&T).
It looks like you've got Gmail set up as IMAP. You can't combine all of that into one folder without losing the usefulness of IMAP (such as everything looking the same regardless of what computer you use to connect to your IMAP account).
If you had Gmail set up as a POP account, then you could combine everything into one place.
