I'm using GitLab v6.2.4.
I have a group named Face Recognition and a project facedetect under it, whose git path name is git@mygitlab:face-recognition/facedetect.git. For some reason, I want to change the git path name to be git@mygitlab:facerecognition/facedetect.git, that is to say, remove the minus punctuation - from the name.
I had try and search but failed to know how to do it. Any one can tell me if there is a method to do it?
Update 1/4/2014: I tried like this

and I got a 404 error The page you were looking for doesn't exist.
