Datamining

[QTip]

I've seen a couple of posts referring to datamining the last couple of days. I'm assuming that this is simply sitting at a table and download hand histories in order to get info on your opponents. To do this, do you have to be sitting at the table? What do you do, sit and the table and then just sit out for a while? I've never done this, but would like to create a larger database in poker tracker.

Anyone have some pointers for me or perhaps another post has addressed this.
