Ah, I get it. That seems to be happening a lot, sadly. The admins of a few groups I'm part of just disappeared in the last few months without leaving anyone else in charge of their group, and contributors as far as I know, can't do it :(. Some even visit DA from time to time, so I don't get it....
I think this is the only one I submitted here, it's just that I resubmitted everytime it expired.
