I'm excited for this, my wife is an accountant and often asks me to help her with VBA macros. I like that someone else had the same working from home experience as I did...aka "can you come look at this form for me, some macro isn't running". I wonder what is the overall percentage of VB macros written, especially in big corporation, by other people than the stated file owners.
