Thanks Galin Nytshade.

I'm glad it has helped at least some people in solving their confusion/problems in getting this working. When I first came here, there was a lot to digest, & quickly felt overwhelmed by the complexity of it all. I tried reading all I could, but even still had questions when things went wrong. After getting no response to a few queries I'd made here on the boards & in IRC, I'd resolved to try & pass along what I'd learned to others who were probably every bit as confused as I was, once I'd gotten the hang of things.
I only ask that each person who this info. has helped please try to help at least one other person who comes here as lost as you once were, if you can.
BTW, I'll be updating this info. (by editing the top post) as new information comes to light, including new databases, so don't be surprised if this info. has changed slightly if you come back to view it again.
