Welcome to "The Advertising Consultant" (TAC) stack. For the stack to display properly, you should have Palatino, Helvetica and Geneva available in your system. Also, monitor color depth should be set to "256 Colors" or LESS.
A word of caution — the material conveyed through TAC is a little dense. I suggest tackling it when you won't be distracted by the press of other business. You also might want to have a pencil, paper and a calculator handy, so you can explore the information on your own — mess with the formulae, try some calculations on your own, and so on.
Aside from this, all of the usual caveats apply, including, but not limited to: you use the stack and the information it conveys at your risk, no warranties are expressed or implied, I and my company are not responsible for damages of any kind (including direct or consequential damages) and you agree to hold us harmless from any and all liability arising from your use or distribution of the stack, and so on.
Finally, PLEASE DO NOT CALL EXPECTING TECHNICAL OR INFORMATIONAL SUPPORT. The telephone number given in the stack is a business line and is reserved for that purpose.
Thanks, and best wishes for your advertising success.
