Change Name character limit to 20

[speedruntrainer]

why? why I need to change my username to wear the [CF]Tag?
I read there is a 16 character limit but can it be changed to 20 so I can use
[CF]speedruntrainer (19 characters) sorry, I don't really like namechanges, but still want the tag.

Thanks.
