Hello EMF nation:)

It was great to meet EMF members from Ireland and Columbia in Chicago
- what a blast.

FAVOR : Please sign your e-mails with your name and country (at the
minimum). This will help us with the research that we are conducting.

Thanks... Also, if you are interested in IXMA and the Brand Week
opportunity, but haven't e-mailed me yet - please do!


My love to all EMF nationals:)
