At this point, I don't even care what the rest of the book is about. I am so amazed. I set up my data source according to the instructions, no problem with that, connected to it with no problem with the letter autopilot, printed those with absolutely no problem, set up and printed the labels for the same addresses with absolutely no problem, and just got back from the post office.Might I add, I couldn't get mail merges to work with Microsoft no matter what I tried.I haven't done anything else yet, but for mail merges from Access address databases, this product and this book ROCK.
