Not Autorized To Search Members By Name

I used to spend a lotta time here getting drunk and being stupid. name was ...jay... which eventually got changed to jay745(i think). I had a thread years ago in the lounge where I posted some pictures I drew. As far as I know, those pictures are gone forever and the only copy MIGHT be posted here someplace. I am not having any luck with search, and when I try to search for my old names it says I dont have authorization to search by member name.
