I don't know how to create a macro to do what you are wanting but I'm sure the experts on this board can help with that. I can help a little using a formula.
In my experience, mailing lists usually are not consistent and sometimes you have to do some sorting and alter your formulas for different types of situations.
In this particular example, it takes the letters from the left up to the first space and adds everything from the & to the right. As I said, you will probably have to tweak this a bit for other unique situations depending upon your data. At least it gives you an idea of what you can do.
Good Luck
