Thanks Gizmo, I didn't think about it that way. I guess I have always been a preferences guy. A lot of my software doesn't have enoguh preferences, although the programmer I use tells me it isn't the easiest thing to program in. But, I suppose for the more hard core users (if that would be the term), choosing the option to opt out rather than in would eliminate many of those who respond as you suggest.
I belong to a lot of users groups. I love the way Experts-Exchange does it.
Thanks very much for your input.
