Setting up Websites at multiple domains on one server

I'm at my wit's end. I've been trying to get several Web sites hosted on the same server for weeks now. I just can't decipher Mac OS X Server set-up. I've played with Workgroup Manager, Server Settings, NetInfo Manger. I just want the server to handle traffic coming to domain1.com from one account on my G4 tower, and to handle traffic coming to domain2.org from a different account. Does it have to be so hard, so confusing? Someone please point me to a hold-your-hand simple guide to doing this. == Steve
