Yep, MD to the rescue. Can change it only once and have to do it through Fandom.

My advice is and always will be to do it as soon as you can. The longer you wait, the more everyone gets to know your old name, the more it might confuse others because existing posts will retain your old name, but that's OK. Your contribution history will move to your new account name but can take longer for Fandom to move you over if you have a very large contributions history. While they are doing that process you will not be able to post, but I've seen few who have done it, and they are all happier that they did because the new name fits them better.

Good Luck and Happy Gaming :--)) - El
