How can I change my name back to what it was?

[bryngelenponies]

I changed my name for Christmas but have no idea how to put it back. I assumed that it would revert automatically but nobody else seems to still have a Christmas one. I have tried everything I can think of and am now at a total loss please help!
P.S. I do mean my H&H name

You need to go to Feeback/Suggestions/Queries at the bottom of the opening page, there's a festive name reversal thread in there!
