I emailed Dustin yesterday, asking him to put my Ages back up, and warning him that he would probably receive multiple requests similar to this in the near future. I just recieved the following reply:
Okay, your Ages are now available again. By the way, the program was written such that anyone could take over at any point. The .dat file is self-explanatory; you merely need to point the update variable to the location of the new server's file. All tools that I used in the preparation of an Age were incorporated into UruAgeManager. If you(pl) prefer to email me the updated .dat file for me to place in the normal location, I will continue to do so indefinately.
So it seems this course is the best way to go, for all of us.
