There is no current rebuild DM. Send your requests to any active DM or ask an available DM on Discord.
Your rebuild isn't done in the server vault, it is physically done in game. Once the rebuild has been approved any DM is able to supervise it. If there changes to stats or feats at first level you will need to remake the PC at level 1. A new name will be needed. Typically people will add an extra space, a symbol stuch as - or ~ ' or remove these if the PC already had them.
You should prepare prior to getting a DM to supervise. Make sure you know what skills and feats you are taking at every level. It's very easy to mess up and I recommend having a list in front of you of what to do at every level. Don't make the mistake of assigning all your skill points at the end since if you die just once you'll lose them all and have to get a DM to help you out!
Get your new PC ready first. Remember to write in your deity field and remember the examine description. Find the portrail/voiceset/skin and hair colour. These things can be time consuming and you don't want to be keeping the DM waiting to start after they've said they can do it there and then.
Once you're ready you can leave the new PC in your vault and play another PC or the old version. Ask once per hour or so to the DM channel if they have time to do an approved rebuild. You can also ask in IRC or message a particular DM who tends to play in your time zonem or reply to a questions/issues shout. If you've having a lot of trouble getting hold of a DM you can ask a PG to organise it for you.
When you get a DM they will look at the old version and write down Alignment points and XP total. They then reduce the old PC to level 1 and kill them. You log in the new one, they give it that XP total and leave you to level up. Once you tell them you are done, they will check every stat, skill point, and feat, fix your alignment points, and give you the loot from the old PC.
The rebuild will be normally be done in a DM only area. They will check every single thing before they port your character onto the normal maps. So if you have made any mistakes with skill points etc, tell them that. They can take you down a level or 2 or 3 to fix things. They will either manually give you the languages according to the rebuild or port you to the lobby to take them.
