Comments and moderator role
One of the ways to communicate with backers is to read and answer their comments. We enable commenting on a project from the draft phase till the end of the pledge manager. This means your backers can leave their feedback whenever they want, and you can respond to their comments. Your name is marked with a "Creator" tag, so your backers will know that your profile is legitimate.
You can invite someone to help you moderate comments in your project by hiding or pinning/unpinnig them. To invite a person to collaborate as a moderator, go to "Users," click "invite collaborators," and choose "moderator" from the list.
A moderator has also the "Creator" tag displayed next to the nickname.
