When I started on Homecoming I got my favorite/mains name from Live as my global. Yay! I could not however get it as her name when I recreated her, so I added an S at the end. Meh, not the same but what do you do. Well I figured out what to do and looked up who had the name and decided I'd try to email them and just explain why I wanted the name and ask if they would part with it. I heard nothing. For months. Then about a year later I got an email from them and they said they would absolutely give it to me! Yay!
I only share this as a positive example of asking the person and it working out. I had given up hope and continued on with my "subpar" name.
