How to leave a collab project and delete my archived projects?

I’ve invited into a collab project as a user role several days ago, and I finished my work, this project doesn’t need me anymore.
I’d like to know is there a way to remove myself from a project, without contact the organizer.

And those archived projects, there are too much of them…is there a way to delete them totally?

Hi coallin,
Unfortunately there isn’t a way for people with “user” access level to a project to remove themselves at this time. Deleting projects completely is not possible, but archiving the project should remove it from the normal dashboard view.
