Currently, per Give users admin permissions, only an Org admin can add another. The Org admin must follow the steps below:
Log in to your organization at admin.atlassian.com.
Choose Settings > Administrators.
Click Add administrators.
Enter an Atlassian account email address and click Grant access.
The problem I have is at step 2. There is no Administrators option.
Go to admin.atlassian.com and click the name of your organization. Then you should find the Settings menu item.
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
