Petition for longer display names

I tried signing up as NorthernLightMountain but couldn't since there seems to be a limit on user name length at 20 characters. (There's a bug for that btw, you won't get an error message if the user name is too long, it just won't submit the form and stalls)

Display names seems to share that limit. Wouldn't mind seeing it raised a bit if possible?

No biggie if not, just hoping I could look like I had imagined :)
