Be sure to track all your donations, labor, effort from the smallest to the biggest. Make it part of your daily, weekly and monthly reporting process to keep track of your giving.
As people give, consider gathering email addresses so you may thank them and let them know how well the effort is going.
When you reach or exceed your goal, let those who participated and donated know of the success. It is great to know an event was successful.
Use a graph or diagram to show the progress and success.
The Fundraising Ideas website provides tool to create and post a thermometer gauge (as you see here) on your website. It took me 10 seconds to create this.
