The one place I've done this before (user names), I check beforehand.
In retrospect, I probably should have done this afterward as well.
I think you pretty much have to check afterward to provide robust code.
But doing it beforehand is a lot easier.
Afterward, it's more difficult to know what caused the problem.
So I have no answers, but I'm paying attention to what answers someone else
comes up with :)
