Hi Joe,

Several messages have been posted regarding the Macro Security setting.

It seems like the best option is to become a trusted publisher.

How does one get a workbook "signed from trusted sources"?

You apply to a Certificate Authority (such as Verisign, Thwate etc) to purchase a
digital signature. You then sign the code using it.

Are Microsoft & Verisign the only enterprises that can certify a trusted publisher?

Personally, I use Thawte, www.thawte.com

Is this costly?

I think it's about $200 per year.
