Oh, so you can see it. Sorry, I found out about it only recently, so I don't recall if it was functional back when I was a plain user. I am pretty sure though that only the staff can delete it
As for the search, this is what I was talking about not working. It indeed only returns our own username. I have asked Ralle about it, but there are no plans in updating it at the moment, given that's it's quite an old tool.
