We've invited some of our customers in our sprintr project. One of them left, so I want to remove him from our sprintr project. I don't see any possibility to do that. I found him @ the project members, but I see no button to remove him. He can only do it by himself. I already filed feedback.
This feature is planned for the next big sprintr release. In the mean time, you can send an email to firstname.lastname@example.org to remove the account from that specific.
