If you've donated to a friend or family member's Fundraising Page, you can change your donation name, message and hide the donation amount here:
http://www.justgiving.com/process/editsponsormessage
Just enter the email address you used to donate and the donation reference number. You'll find this in the email receipt that we sent to you when you completed your donation.
You can change the message or anonymise old donations too, which will also remove them from other people's Feeds. Just log into your account on a pc or laptop and click on your name and 'Donations you've made' in the top right hand corner. Click 'Print' next to the relevant donation to find the donation reference number.
