How do I add a subsidiary user to my account?

[ifoundpete]

I want to grant a colleague limited access to my account so he can step in and review some of my Moz reports and/or edit some of the campaigns.  Is that possible?  If so, what are my options?  Thanks.

I've seen lots of questions about adding other users and it sounds like it's something Moz is working on but they currently only allow one user per account. https://seomoz.zendesk.com/entries/20199538
