First thing.. Most people d not do anything after inviting the blood bank. In that case blood bank takes care of all the work. So generally speaking.. you need not do any of the work in this section..
But, looking at the other side, We are sure each one of you will like to ensure all the donors have a very good donation experience. We are sure you will like to make people so confident about blood donation that they can inspire others. And we are sure that you would like to have a Wonderful Blood Donation camp rather than another event . And for this.. some extra effort is required from your side.
