Under the Events & Campaigns tab you will see the option to "create new event" on the right.
Select "project fundraiser"
Fill in all of your campaign logistics including: name, date, custom URL and fundraising goal and social media options.
Click "create campaign and edit this project".
The campaign will be in draft mode (see red notification on left of page), until you "make campaign live" by clicking on the green button. In draft mode, only you and other logged in administrators can view it.
You can make other edits here including: adding a banner, YouTube or Vimeo video, images and text for your project page.
Additional options in the left-hand editor allow you to add fundraising page creation, team fundraising, leaderboards, a countdown timer until your campaign opens, as well as custom giving levels.
