You can include other admins as part of your organization/subset/campaign in 2 different ways. You can send them an invite directly from your dashboard via email. This email will include the passcode which allows them to join you as an admin. The second way is to simply provide them the 6-digit code (also found in your dashboard) and they can use that code upon registering from the sign up page.
Also, from the dashboard, already registered admins have the ability to join other organizations, subsets, or campaigns by clicking the ‘join or create’ link. This will also require them to enter the passcode. If you have any further questions on this or need any assistance on joining or inviting and admin to your organization/subset/campaign, please contact a FunRaisen representative via email at support@funraisen.com and we will gladly assist.
