I mistakenly deleted a person from a project and I couldn’t figure out how to add him back again.

Afterward, I found that I could Add the person back very easily by going back to the Dashboard, clicking on the ‘All People’ tab, and then ‘Edit’ under his name. There, I was able to give him access using a checkbox on the right…

Hope this helps anyone else who might be in a panic like I was!

Cheers!~
