Seeing all the attendees, sponsors and donors as a group - the forest - misses their significance as individual donors - the trees. Assuming the only relationship these folks have with you is the event ignores the value of their long-term support and presumes they know more about your organization than they do. It is likely they have no idea what you really need, what plans you have for the future of your organization, or even how else they might help you.
This is a classic case of missed opportunity: seeing the forest - one big group - rather than the individual trees - specific prospects. So ask the board members to pay a visit to those who have supported you for multiple years and deepen the individual relationship that you already have with these supporters. It will result in major gifts over time. People can't help you if they don't know what you want.
