You can back any project as normal. Once the project is funded, we will request the project's owner to generate a backer report. This will allow the owner to know which of our members has backed the project. You can also notify the project creator if you are a member of BackerCity while backing the project.
If the creator fails to provide the special reward they have promised, please leave a comment here or write to our customer service team at
