Ok, how you do this is simple. Make a web page somewhere that looks like this:
10/28/89
11/30/91
12/28/92
12/29/92
etc etc.
In other words, type in the shows that you have seen, using the "br" tag to separate the lines. My Phish page is at http://www.ihoz.com/seedfile.html. Once you've uploaded the page somewhere, type in the URL in the line below. DBR Stats will use that seed file of set lists to generate your stats. This way you don't have to select all of the shows you have seen every time.
