More Big Tips Please

Of course Adrian, I've got loads.

How about this one:

When you do a combined request you can't change the column headings in the Edit Column Formula window as any changes you make there aren't saved. However, you can change the column name in the Column Properties \ Column Format window just fine.
(I have better tips than this but I'm just warming up).

Surely someone out there can challenge Phil to tip showdown?
