Suggested feature "DoneIt" Answered
An inspiration from Geocaching. It would be cool to have a feature where members could check a box and post a pic/vid when they have completed a certain instructable. The "DoneIts" should show up on both the "doers" user/profile page, as well as the instructable owner. You could also leave a short note on what you may have done different, or any tips and tricks used to complete the project.
