In my earlier Gitlab installation was an admin area to manage some things. With Version Gitlab CE 8.15 I cannot find the admin area. Can somebody tell me, where I can find it?

Oh, what a stupid thing. I did not remember, how that happens, but I found a very good password on a note and did tried that for the root user - success! I did not remember that process during the installation… Sorry - and thank you for your help!
