You took the time to make your campaign, shared it probably a few times and got disappointed, don’t be disappointed, nobody ever said it was easy, however stop sharing means for sure nothing will come, make emails to your friends, share it on Facebook, do not expect because you made the fundraiser people will find it by them self. Why did you make it in the first place? because you need help make sure people see your fundraiser and do not stop promoting it! Like with everything else it takes time and some effort from your part. Go over your fundraiser and make sure it has all points covered, what you going to do with the funds, who you are etc.
