Add or Remove Other Owners
Basecamp 4 accounts can have more than one owner, so the original owner can designate additional people as owners — handy (and recommended!) for when you're out of the office having a baby or something, and your credit card expires! You don't want to have to talk to Basecamp support while you're in labor, do you? Of course not. But seriously, adding a backup account owner really is a good idea.
Start by clicking
Adminland on the top right of the Home page just beneath your avatar:
Once in Adminland, scroll down and click the
Add/remove account owners option:
Type and select the new co-owner's name in the "Choose a person" field located at the bottom and click the
Grant account owner powers button. To remove account owner powers, click the
Revoke button located to the right of the user's name.
