Name changes are done through the character manager here on forums, but exceptions have to be made to ironmen because of their limitations of what they can trade or do. So we'll do the following workaround:

1) you place a gold sub on a regular account of yours
2) PM me the name you want your ironman changed to (you can try checking high scores to see if the name is taken, if unhidden)
3) i delete the gold sub off your reg char and commit the name change
