Entirely variable, depends on how much time you want to put in. If all you do is handle the error messages an hour a day will most likely cover it most of the time. If you personally help all the subscribers with problems that's extra time, some days you'll get none, others you'll be flooded (usually when you really don't have time to do it, and errors are at their worst, but you do it anyway and to hell with what you should *really* be doing). It takes as much time as you want to put into it. Douglas Douglas Winship Hays County, Texas [log in to unmask] Secondary AUTOCAT Listowner MEDLAB-L
