How do I change my user title?

[Miss Modular]

I noticed that we now have the option to create our own user title. I tried changing my title, but I keep running into two problems:

1.) Character Limit. I was hoping to use the title "Lady Schadenfreude" (or whatever title Sethomas suggested for me years ago), but it looks like I won't be able to do it.

2.) When I tried changing it, it won't save. I'm still "Mocker".
