how do i get the gift match for my donation to concrete hero?
Go to your personal profile on this site. You can access from the home page (at the top neat the sign in/log out button) or from the Volunteer page.
Once you are in your personal profile, there is a link on the right side of the page that says "Record individual hours and request a Partner Match." Click on the link, which will take you to a page that ask for the organization information, how much you donated, etc.
